TM124MBJ36F
The TM124MBJ36F is a 4-MByte DRAM organized as four times 1 048 576 × 9 in a 72-pin SIMM. The SIMM
is composed of two TMS418160DZ 1 048 576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package, and
one TMS44460DJ 1 048 576 × 4-bit DRAM in a 24 / 26-lead plastic SOJ package mounted on a substrate with
decoupling capacitors. The TMS418160DZ and TMS44460DJ are described in the TMS418160 and
TMS44460 data sheets, respectively. The TM124MBJ36F SIMM is available in the single-sided BJ leadless
module for use with sockets.
TM248NBJ36F
The TM248NBJ36F is an 8-MByte DRAM organized as four times 2 097 152 × 9 in a 72-pin SIMM. The SIMM
is composed of four TMS418160DZ 1 048 576 × 16-bit DRAMs, each in a 42-lead plastic SOJ package, and
two TMS44460DJ 1 048 576 × 4-bit DRAMs, each in a 24 / 26-lead plastic SOJ package mounted on a substrate
with decoupling capacitors. The TMS418160DZ and TMS44460DJ are described in the TMS418160 and
TMS44460 data sheets, respectively. The TM248NBJ36F SIMM is available in the double-sided BJ leadless
module for use with sockets.
