description
The TM124MBK36E is a dynamic random-access memory (RAM) organized as four times 1048576 × 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 dynamic RAMs, each in a 20/26-lead plastic small-outline
J-lead (SOJ) package, and two TMS42260DJ, 1 048 576 × 2-bit dual-CAS dynamic RAMs, each in a 24/26-lead
plastic small-outline J-lead (SOJ) package, mounted on a substrate with decoupling capacitors. Each
TMS44400DJ or TMS42260DJ is described in the TMS44400 or TMS42260 data sheet, respectively.
The TM124MBK36E is available in the single-sided BK leadless module for use with sockets. It features RAS
access times of 60 ns, 70 ns, and 80 ns. This device is characterized for operation from 0°C to 70°C.

operation
The TM124MBK36E operates as eight TMS44400DJs and two TMS42260DJs connected as shown in the
functional block diagram and Table 1. The common I/O feature dictates the use of early write cycles to prevent
contention on D and Q.
