CAES UT8SDMQ64M48 SDRAM

CAES has an extensive memory portfolio developed to handle the demands of harsh space and terrestrial environments.

The UT8SDMQ64M48 is a high performance, highly integrated Synchronous Dynamic Random Access Memory (SDRAM) multi-chip module (MCM).  The device is 3.0Gb in density and organized as 64Mx48 (16M x 48 x 4 banks). Read and write accesses to the DRAM are burst oriented; an auto-refresh mode is provided, along with a power-saving, power-down mode. Ideal for fault tolerant systems.
