Description
The GLT440L16 is a 262,144 x 16 bit
high-performance CMOS dynamic random
access memory. The GLT44016 offers Fast
Page mode with Extended Data Output, and
has both BYTE WRITE and WORD WRITE
access cycles via two CAS pins. The
GLT440L16 has symmetric address and
accepts 512-cycle refresh in 8ms interval.
All inputs are TTL compatible. EDO
Page Mode operation allows random access
up to 512 x 16 bits within a page, with cycle
time as short as 14ns.
The GLT440L16 is best suited for
graphics, and DSP applications requiring
high performance memories.
