MT18LD272A - Micron Technology

MT18LD272A (MT18LD272A / MT18LD472A) NONBUFFERED DRAM DIMMs

The MT9LD272A(X) and MT18LD472A(X) are randomly accessed 16MB and 32MB memories organized in a x72 configuration. They are specially processed to operate from 3V to 3.6V for low-voltage memory systems. During READ or WRITE cycles, each bit is uniquely addressed through the 21/22 address bits, which are entered 11 bits (A0 -A10) at RAS# time and 10/11 bits (A.
