DESCRIPTION
The 1+51 IS41C8512 and IS41LV8512 is a 524,288 x 8-bit
high-performance CMOS Dynamic Random Access Memories.
The IS41C8512 offer an accelerated cycle access called EDO
Page Mode. EDO Page Mode allows 512 random accesses
within a single row with access cycle time as short as 10 ns per
8-bit.
These features make the IS41C8512and IS41LV8512 ideally
suited for high-bandwidth graphics, digital signal processing,
high-performance computing systems, and peripheral
applications.
The IS41C8512 is packaged in a 28-pin 400mil SOJ and
400mil TSOP-2.
