概觀

The IS41C16257C and IS41LV16257C are 262,144 x 16-bit high-performance CMOS Dynamic Random Access Memories. Fast Page Mode allows 512 random accesses within a single row with access cycle time as short as 14 ns per 16-bit word. It is asynchronous, as it does not require a clock signal input to synchronize commands and I/O.
