The TM124MBK36B is a dynamic random-access memory (DRAM) organized as four times 1 048 576 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 TMS44400DJ, 1 048 576 x 4-bit DRAMs, each in 20/26-lead plastic small-outline J-lead packages (SOJs), and one TMS44460DJ, 1 048 576 x 4-bit Quad-CAS DRAM in a 24/26-lead plastic small-outline J-lead package (SOJ), mounted on a substrate with decoupling capacitors. Each TMS44400DJ and TMS44460DJ is described in the TMS44400 or TMS44460 data sheet, respectively. The TM124MBK36B is available in the single-sided BK leadless module for use with sockets. The TM124MBK36B features RAS access times of 60 ns, 70 ns, and 80 ns. This device is rated for operation from 0C to 70C.
