TM248NBK36B (continued)
The TM124NBK36B is available in the double-sided BK leadless module for use with sockets.
The TM124NBK36B features RAS access times of 60 ns, 70 ns, and 80 ns. This device is rated for operation

operation
TM124MBK36B
The TM124MBK36B operates as eight TMS44400DJs and one TMS44460DJ connected as shown in the
functional block diagram and Table 1. The parity bits are provided by the TMS44460DJ and are controlled by
RAS2. To ensure proper parity bit operation all memory accesses should include a RAS2 pulse. Refer to the
TMS44400 and TMS44460 data sheets for details of operation. The common I/O feature dictates the use of
early write cycles to prevent contention on D and Q.
TM248NBK36B
The TM248NBK36B operates as sixteen TMS44400DJs and two TMS44460DJs connected as shown in the
functional block diagram and Table 1. The parity bits are provided by the TMS44460DJ and are controlled by
RAS2 on side 1 and RAS3 on side 2. To ensure proper parity bit operation, all memory accesses should include
a RAS2 or RAS3 pulse. Refer to the TMS44400 and TMS44460 data sheets for details of operation. The
common I/O feature dictates the use of early write cycles to prevent contention on D and Q.
