8 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 mounted on a substrate with decoupling capacitors. The TMS418160DZ is
described in the TMS418160 data sheet. The TM124BBJ32F SIMM is available in the single-sided BJ-leadless
module for use with sockets.

TM248CBJ32F SIMM is available in the double-sided BJ-leadless module for use with sockets.
operation
The TM124BBJ32F operates as two TMS418160DZs connected as shown in the functional block diagram and
Table 1. The TM248CBJ32F operates as four TMS418160DZs 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
Part numbers in this data sheet are for the gold-tabbed version; the information applies to both gold-tabbed and solder-tabbed versions.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
