description

TM124MBK36B

The TM124MBK36B is a dynamic random-access memory (DRAM) organized as four times 1 048 576 × 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 × 4-bit DRAMs, each in 20/26-lead plastic small-outline J-lead

packages (SOJs), and one TMS44460DJ, 1 048 576 × 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 0°C to 70°C.

TM248NBK36B

The TM248NBK36B is a DRAM organized as four times 2 097 152 × 9 (bit 9 is generally used for parity) in a

72-pin leadless SIMM. The SIMM is composed of sixteen TMS44400DJ, 1 048 576 × 4-bit DRAMs, each in

20/26-lead plastic small-outline J-lead packages (SOJs), and two TMS44460DJ, 1 048 576 × 4-bit Quad-CAS

DRAMs, each 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 and TMS44460

data sheet, respectively.
