Description

The ISSI IS41C16257 and the IS41LV16257 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 12 ns per 16-bit word. The Byte Write control, of upper and lower byte, makes these devices ideal for use in 16-and 32-bit wide data bus systems.

These features make the IS41C16257 and the IS41LV16257 ideally suited for high band-width graphics, digital signal processing, high-performance computing systems, and peripheral applications.

The IS41C16257 and the IS41LV16257 are packaged in a 40-pin, 400-mil SOJ and TSOP (Type II).
