SUMMARY DESCRIPTION

The M69KB096AA is a 64 Mbit (67,108,864 bit) PSRAM, organized as 4,194,304 words by 16 bits. The memory array is implemented using a one transistor-per-cell topology, to achieve bigger array sizes.

This device is a high-speed CMOS, dynamic random-access memory. It provides a high-density solution for low-power handheld applications.
