The TM497MBK36I is a 144M-bit dynamic random-access memory (DRAM) device organized as four times 4194304 × 9 (bit 9 generally is used for parity) in a 72-pin leadless single-in-line memory module (SIMM). The SIMM is composed of eight TMS417400ADJ, 4 194 304 × 4-bit DRAMs in 24/26-lead plastic SOJ packages, and four TMS44100DJ, 4 194 304 × 1-bit DRAMs in 20/26-lead plastic SOJ packages mounted on a substrate with decoupling capacitors.  TM497MBK36I and TMS44100DJ are described in the TMS417400A and TMS44100 data sheets (literature numbers SMKS889 and SMHS561, respectively).

The TM497MBK36I is available in a double-sided, BK, leadless module for use with sockets. The TM497MBK36H/ I featuresRAS access times of 60, 70, and 80 ns. This device is characterized for operation from 0°C to 70°C.
