DESCRIPTION
The
ISSI
IS41C16100 and IS41LV16100 are 1,048,576 x 16-bit
high-performance CMOS Dynamic Random Access Memories.
These devices offer an accelerated cycle access called EDO Page
Mode. EDO 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
IS41C16100 deal for use n 16-bit and 32-bit wide data bus systems.
These features make the IS41C16100and IS41LV16100 deally suited
for high-bandwidth graphics, digital signal processing, high-
performance computing systems, and peripheral applications.
The IS41C16100 and IS41LV16100 are packaged in a 42-pin 400-
mil SOJ and 400-mil 50- (44-) pin TSOP (Type II). The ead-free 400-
mil 50- (44-) option is available too.
