description

The TMS418160A is a 16 777 216-bit dynamic

random-access memory (DRAM) device orga-

nized as 1 048 576 words of 16 bits. It employs

state-of-the-art technology for high performance,

reliability, and low power at low cost.

This device features maximum RAS access times

of 50-, 60-, and 70 ns. All address and data-in lines

are latched on chip to simplify system design.

Data out is unlatched to allow greater system

flexibility.

The TMS418160A is offered in a 42-lead plastic

surface-mount SOJ package (DZ suffix). This

package is designed for operation from 0

° to 70°C.

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.
