DESCRIPTION

The

16-bit high-performance CMOS Dynamic Random Access

Memories. .ast Page Mode allows 1,024 random accesses

within a single row with access cycle time as short as 20 ns per

16-bit word. The Byte Write control, of upper and lower byte,

makes the IC41C16105S ideal for use in 16-, 32-bit wide data

bus systems.

These features make the IC41C16105S and IC41LV16105S

ideally suited for high-bandwidth graphics, digital signal

processing, high-performance computing systems, and

peripheral applications.

The IC41C16105S and IC41LV16105S are packaged in a

42-pin 400mil SOJ and 400mil 44- (50-) pin TSOP-2.
