1. DRAM-Chip-to-Module-Size-Correlation Single In-line Memory Modules (SIMM) are available as 30-pin modules with 8Bit data width (with parity: 9Bit) or 72-pin modules with 32Bit data width (with parity: 36Bit). The data capacity of a module is given in MegaByte (1 MegaByte= 1 MByte= 1 MB) and 1 Byte is eqivalent to a data width from 8 Bit.

Small Outline J-Lead (SOJ)

Thin Small Outline Package Type II (TSOP Type II)

Common used packages of the soldered DRAM chips are Thin Small Outline Package Type II (TSOP Type II) or Small Outline J-Lead (SOJ)

30-pin modules are available in 256kB, 1MB, 2MB, 4MB, 8MB and 16MB with or without parity and 2, 4 or 8 data chips per module. Normally the chips are placed one-sided only.

72-pin modules (also called PS/2) are available in 1MB, 2MB, 4MB, 8MB, 16MB, 32MB, 64MB and 128MB with or without parity in both EDO and FPM type and 2, 4, 8 or 16 data chips. The chips are placed one-sided or on both sides.

Looking at the number of pins on each individual data chip on the module can give you an idea of the data capacity of the chips and thus the module. Remember the Number-of-Pins-to-Data-Capacity-per-Chip-Correlation:

A module with 8 chips in SOJ-package and each 24 pins in 4 sets of 6 pins (--> 16MBit Chip) has a data capacity from 16MByte because 16MBit x 8 Chips ---------------- = 16MByte 8Bit/Byte and a module with 4 chips in TSO-package and each 32 pins in 4 sets of 8 pins (--> 64MBit Chip) has a data capacity from 32MByte because 64MBit x 4 Chips ---------------- = 32MByte 8Bit/Byte

This foto (found somewhere on the Internet) shows a very rare item: a 30-Pin SIM- Module with a data capacity from 16 MByte. It is difficult to read the part number (maybe xx16100), but the memory chips with 24 pins in 4 groups to 6 pins allow the identification.

The charts below provide information for common Chip-to-Module-Size-Correlation. The number of pins per chip relates to common TSOP Type II- or SOJ- package with each 4 sets of pins:

2. Some Examples Chip name: HYB514100BJ-60, Number of chips on module: 9, Number of pins: 30

HYB51 4 1 00 BJ -60 HYB designates a Siemens device, the 51 designates a 5V device, the 4 designates a 4MBit chip, the 1 designates 1 bit data width, the 00 designates a FPM device and least the -60 indicates the speed of 60ns. The chip is thus 4MBit (4Mx1) 60ns FPM. If there are 9 such chips on the 30pin SIMM module, then it is 4Mx1x9=4Mx9. This is a 4 MByte 30pin FPM module with parity. 1st Chip name: uPD4217400-60 Number of chips on module: 2 and 2nd Chip name: uPD424100-60, Number of chips on module: 1, Number of Pins: 30

The uPD denotes it is a NEC device Data chips: uPD42 17 4 00 -60 The 17 designates a 16 MBit chip with 2k refresh. The 4 designates 4 bits data width. The 00 designates a FPM device. The -60 indicates a speed of 60ns. The data chip is thus a 16 MBit (4Mx4) FPM 60ns device.

Parity chips: uPD42 4 1 00-60 The 4 designates a 4 MBit chip The 1 designates 1 bit data width. The 00 designates a FPM device. The -60 indicates a speed of 60ns. The parity chip is thus a 4 MBit (4Mx1) FPM 60ns device. If there are 2 data chips and 1 parity chips on the module, then we have 4Mx4x2 + 4Mx1x1 = 4Mx8 + 4Mx1 = 4Mx9. This is a 4 MByte 30pin FPM module with parity. Chip name: MCM54400-70, Number of chips on module: 8, Number of pins: 72

MCM5 4 4 00 -70 The MCM designates a Motorola device. The first 4 designates a 4 MBit chip and the second 4 designates 4 bits data width. The 00 designates a fast page device and least the -70 indicates a speed of 70ns. The chip is thus 4 MBit (1Mx4) 70ns FPM. If there are 8 such chips on the 72pin SIMM module, then it is 1Mx4x8=1Mx32. This is a 4 MByte 72pin FPM module with no parity. Chip name: MB8118165-70, Number of chips on module: 2, Number of Pins: 72

MB81 18 16 5-70 The MB designates a Fujitsu device. The 18 designates a 16 MBit chip with 1k refresh and the 16 designates 16 bits data width. The 5 designates an EDO device. The -70 indicates a speed of 70ns. The chip is thus 16 MBit (1Mx16) 70ns EDO. If there are 2 such chips on a 72pin simm module, then it is 1Mx16x2=1Mx32. This is a 4 MByte 72pin FPM module with no parity. Chip name: HY514400-60, Number of chips on module: 16, Number of Pins: 72

HY51 4 4 00 -60 The H5M designates a Hyundai device The first 4 designates a 4 MBit chip. The second 4 designates 4 bit data width. The 00 designates a FPM device. Least the -6 indicates a speed of 60ns. The chip is thus 4 MBit (1Mx4) 60ns FPM. If there are 16 such chips on a 72pin SIMM, then it is 2x1Mx4x8=2Mx32. This is a 8 MByte 72pin FPM module without parity.

2. How to decrypt the OnChip Code In the late 1980s the most common DRAM types were PM (Page Mode) and FPM (Fast Page Mode). In early 1990s the most common types were FPM and FPM with EDO (Extended Data Out). Generally each manufacturer uses his own scheme to mark memory chips. However, a simple algorithm can be used in most cases to determine the exact type of chip. Usually the number starts with two or three characters which are specific to the manufacturer. For an FPM, nibble, SC or EDO chip the rest of the sequence is usually up to 16 Mbit chips built up more or less the same : first an indication of the manufacturer, total memory and refresh address range is given, then the number of bits per chip, then the mode of operation terminating with the memory speed (for manufacturers specific part number code decoding see the Part Number Chart).
