Description

TM248NBJ36F
The TM248NBJ36F is a 4-MByte DRAM organized as four times 1048576 × 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 1048576 × 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 2097152 × 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 1048576 × 4-bit DRAMs, each in a 24/26-lead plastic SOJ package mounted on a substrate with decoupling capacitors. The TM248NBJ36F 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.
