16-bit high-performance CMOS Dynamic Random Access
Memories. 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.
DESCRIPTION
