Memory Chips, Controllers and the Components on the Board

Chip Off Data Recovery and Integrated Circuit Analysis

When the evidence is a chip, reading it is only half the work; the other half is proving what the result means for the device, the data and the dispute. Global Digital Forensics reads memory components and controllers through chip off removal and in system access, decodes what comes back and reports it in terms a court can follow.

The Question Decides How the Chip Is Read

An integrated circuit examination can concern the data a memory chip still holds, the behavior of a controller, the failure of a component, a suspect or substituted part, or hardware someone claims was tampered with. Each calls for different observations, so we begin with the component, its markings, the board it came from, the comparison material available and the question the matter must answer, and build the plan from there.

The bench work is ours. Veronica Perez, our Senior Computer Forensic Specialist, trained with Teel Technologies in JTAG, chip off, in system programming and embedded hardware analysis and completed iPadRehab microsoldering training in 2024, and that training covers component identification, removal, reading and the decoding of the data. When a question needs destructive materials analysis beyond our bench, the proposal names the qualified laboratory, the comparison samples and the specialist before anything is commissioned.

We test defined hypotheses against the manufacturer documentation. Counterfeit screening, reliability testing and tampering analysis are separate assignments with their own evidence rules, and where suspect parts are the issue the scope follows SAE AS6171, the test methods standard for suspect counterfeit electronic parts. Component pedigree rests on traceability records and intent rests on evidence beyond the test bench, and the report keeps each finding tied to the evidence that carries it.

Before the board is pulled or the part ships anywhere, call (800) 868-8189 and describe the component. The handling decision made on that call keeps every later method available.

Methodology

How the Component Evidence Is Examined

Identify the component and the access options

Package, markings, architecture, interfaces, memory type and power state identified, and the risk of each access method weighed before the sequence is set.
Preserve the component and its condition record

The source photographed and documented before it is touched, starting with the least intrusive repeatable method so later work keeps its options.
Acquire the data in a written, approved sequence

Supported interfaces, in system programming or chip off reading, each step validated and recorded.
Correlate the technical findings

Acquired data read alongside firmware, component condition, external records and known system behavior, so no artifact is interpreted in isolation.

Evidence commonly examined

Component Evidence We Examine

Devices, modules and circuit assemblies provide the physical source and the board context. Flash memory and firmware images supply the binary material, and interface captures and diagnostic records show how the component communicated or behaved. Configuration, calibration and event data tie settings to recorded operation, reference components and manufacturer documentation give the comparison basis for any difference, and photographs and handling records document the condition of the part and every change made to it.

What you can expect

Describe the devices and the deadline and the first call sets the plan.

Acquired Records and Technical Findings

You receive a source condition and method record showing what was received and the sequence of work, verified binary images and extracted artifacts, an analysis tying the observations to the agreed question, and a technical report and exhibits with the expert support the matter needs.

Bring the Component to a Hardware Examiner First

Bring the component, the question and the deadline to a free initial consultation. We cover feasibility, relevant experience, conflicts and any laboratory work before defining the assignment, so you know what the examination can reach before you commit to it.

Technical methods and scope

Function, Construction, Provenance and Stored Data Kept Separate

An integrated circuit examination may address failure, counterfeit substitution, damage, manufacturing variation, hardware integrity or retained memory contents. We record the package, markings, lot and board context, electrical condition and comparison samples, then separate the questions so the right method is applied to each.

Examine the Component Before Anything Opens It

Visual records, measurements, marking comparisons and electrical screening can reveal package anomalies, rework, corrosion or unexpected construction before any irreversible step. Where the question needs imaging beyond the bench, we coordinate it through the assigned laboratory and record the conditions behind each image.

Comparison quality decides the finding. A difference from a reference device can reflect a legitimate revision, a different factory, a date code or a packaging change, so the report records the reference population and the basis for treating a variation as expected, unexplained or material.

Tell us what happened and when, and a senior examiner will say which sources to secure first.

Destructive Analysis Only Under Written Authority

Chip off removal and any laboratory materials work permanently alter the source. We obtain written approval first and document the sequence with images before and after each material step, so the plan preserves the options later questions will need.

When a qualified laboratory performs a stage, the report names who did it and keeps the laboratory observations apart from opinions about cause, origin or intent.

Counterfeit and Hardware Integrity Questions

For counterfeit questions the examination can compare markings, package construction, electrical behavior and traceability records. Hardware integrity work can compare layout or function with known good design material and test unexplained circuitry or behavior. We weigh the combined evidence, because a counterfeit or implant finding rests on several independent observations agreeing.

When memory contents are the question, raw acquisition and decoding form their own workstream. Controller translation, error correction, encryption and application structures all stand between a raw read and usable information, and we work through each before describing what the chip contained.

Ask an examiner how this applies to your matter; the first consultation is free.

Laboratory Record and Expert Reporting

Deliverables can include intake and custody records, high resolution images, test conditions, instrument output, comparison tables, extracted data and a technical report. The report identifies any subcontracted work and every destructive change, and ties each opinion to its supporting evidence, so there is a clear record of who did what and what it shows.

Scoping a Chip Level Examination

What should we define before an integrated circuit examination?

The component, the condition of the board it sits on and the data or technical question you need answered. We use those to plan the feasibility work and to identify any destructive step that will need written approval.

What information helps scope a chip examination?

The device the chip came from, its condition, its power state and the question in dispute. Leave the device as it is until you have preservation guidance, because a power cycle or a repair attempt can change what the chip holds.

Can you confirm in advance what data can be recovered?

Feasibility is the first thing we establish. It depends on the memory type, the condition of the package, the encryption and controller translation in play and the access methods the component supports, and you hear the realistic result before the deeper work is commissioned.

How are evidence handling and reporting agreed?

Authority, transfer, methods, destructive steps and reporting are set out in the engagement scope, together with the qualifications of whoever performs each stage and any testimony the matter needs.

Free consultation

Describe the Component Before It Ships

On the first call an examiner asks what the device is, what condition the chip and board are in and what the matter needs to prove, tells you how to store and transport it, and outlines the access method, any laboratory stage and the timing.
