DESCRIPTION

TheICSI IC41C1664 and IC41LV1664 is a 65,536 x 16-bit high performance CMOS Dynamic Random Access Memories. The IC41C1664 offer an accelerated cycle access called EDO Page Mode. EDO Page Mode allows 256 random accesses within a single row with access cycle time as short as 10 ns per 16-bit word. The Byte Write control, of upper and lower byte, makes the IC41C1664 ideal for use in 16-, 32-bit wide data bus systems.

These features make the IC41C1664 and IC41LV1664 ideally suited for high-bandwidth graphics, digital signal processing, high-performance computing systems, and peripheral applications.

The IC41C1664 is packaged in a 40-pin 400mil SOJ and 400mil TSOP-2.
