description
TM124BBK32
The TM124BBK32 is a dynamic random-access memory (DRAM) organized as four times 1048576
×
8 in a
72-pin leadless single in-line memory module (SIMM). The SIMM is composed of eight TMS44400, 1048576
×
4-bit DRAMs, each in 20/26-lead plastic SOJ packages, mounted on a substrate together with decoupling
capacitors. Each TMS44400 is described in the TMS44400 data sheet.
The TM124BBK32 is available in the single-sided BK leadless module for use with sockets.
The TM124BBK32 features RAS access times of 60 ns, 70 ns and 80 ns. This device is rated for operation from

operation
TM124BBK32
The TM124BBK32 operates as eight TMS44400DJs connected as shown in the functional block diagram. Refer
to the TMS44400 data sheet for details of operation. The common I/O feature of the TM124BBK32 dictates the
use of early write cycles to prevent contention on D and Q.
Part numbers in this data sheet are for the gold-tabbed version; the information applies to both gold-tabbed and solder-tabbed versions.
