DESCRIPTION
The ICSI IS41C16256 and IS41LV16256 is a 262,144 x 16-
bit high-performance CMOS Dynamic Random Access Memo-
ries. The IS41C16256 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 16-bit word. The Byte Write control, of upper and
lower byte, makes the IS41C16256 ideal for use in
16-, 32-bit wide data bus systems.
These features make the IS41C16256and IS41LV16256 ideally
suited for high-bandwidth graphics, digital signal processing,
high-performance computing systems, and peripheral
applications.
