DESCRIPTION
The
16-bit high-performance CMOS Dynamic Random Access Memo-
ries. Fast 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 IS41C16105
ideal for use in 16-, 32-bit wide data bus systems.
These features make the IS41C16105 and IS41LV16105 ideally
suited for high-bandwidth graphics, digital signal processing, high-
performance computing systems, and peripheral applications.
The IS41C16105 and IS41LV16105 are packaged in a
42-pin 400-mil SOJ and 400-mil 44- (50-) pin TSOP (Type II).
