1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.


Description

The ICSI IC41C16257 and the IC41LV16257 are 262,144 x 16-bit high-performance CMOS Dynamic Random Access Memory. 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-, 32-bit wide data bus systems.

These features make the IC41C16257 and the IC41LV16257 ideally suited for high band-width graphics, digital signal processing, high-performance computing systems, and peripheral applications.

The IC41C16257 and the IC41LV16257 are packaged in a 40-pin, 400mil SOJ and TSOP-2.
