Introduction: Navigating through the intricacies of memory chip versions can be challenging. In this post, we'll delve into the identification methods and code deciphering for memory chips from various manufacturers. Let's start with a breakdown of the major players in the game.
1. Samsung: Samsung's official nomenclature is detailed in their official document here.
Example:
The first line "SEC 843" indicates that "843" represents the memory chip's production date.
The second line "K4A4G08" reveals that "4G08" denotes the memory chip's capacity and bit width – a 4Gb 8-bit chip (AG represents a 16Gb capacity).
The third line "5WT BCTD" specifies the chip version (T-DIE) and frequency/timing details.
Samsung's known chips include A-DIE (16Gb, 32Gb), B-DIE (8Gb, 16Gb), C-DIE (8Gb), D-DIE (4Gb, 8Gb), E-DIE (4Gb), F-DIE (4Gb), M-DIE (16Gb), S-DIE (4Gb, 8Gb), and T-DIE (4Gb).
2. Micron (Crucial): Micron's chip identification is explained in their official documentation.
Example:
The part number MT40A1G8SA-075:E corresponds to a DDR4 chip with an 8Gb 8-bit capacity, 2666 C19 frequency, and E-DIE version.
Micron's chips and core code correspondence can be found in their documentation.
3. Spectek: Spectek's chip naming conventions are outlined here.
Example:
The code SUU512M16Z11BD8LY indicates a 512M16 chip with Z11B core code (refer to the documentation for core code details).
Spectek's chip quality grade is represented by TP in their coding.
4. Hynix: Hynix's official naming document can be accessed here.
Example:
The second line "H5AN8G8NCJR" reveals an 8Gb 8-bit chip with the C-DIE version.
Hynix's chip coding includes information on capacity, version, and frequency/timing.
5. Nanya: Nanya's official documentation can be found here.
Example:
The first line "NANYA 1804" indicates that "1804" represents the chip's production date.
The second line "NT5AD1024M8A3-GZ" shows an 8Gb 8-bit chip, A-DIE version, and 2400 C17 frequency.
Nanya's chip coding includes production date, capacity, version, and frequency/timing details.
6. Powerchip: Powerchip predominantly uses ETT (Engineered Test Transistor) chips, lacking a specific naming convention.
Example:
An ETT chip may be referred to as "C3G-T."
