The TM497MBM36A is a 16-megabyte dynamic random-access memory ( DRAM) organized as four times 4 194 304 x 9 (bit 9 is generally used for parity) in a 72-pin leadless single in-line memory module (SIMM). The SIMM is composed of eight TMS417400DJ 4 194 304 x 4-bit DRAMs, each in a 24 / 26-lead plastic small-outline J-lead (SOJ) package, and four TMS44100DJ 4 194 304 x 1-bit DRAMs, each in a 20 / 26-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TMS417400DJ and TMS44100DJ are described in the TMS417400 and TMS44100 data sheets, respectively. The TM497MBM36A SIMM is available in the single-sided, BM leadless module for use with sockets.
