DESCRIPTION

TheISSI IS41C8205andIS41LV8205are2,097,152x8-bithigh-

performance CMOS Dynamic Random Access Memory.

The Fast Page Mode allows 2,048 random accesses

within a single row with access cycle time as short as 20

ns per 4-bit word.

These features make the IS41C8205 and IS41LV8205

ideally suited for high-bandwidth graphics, digital signal

processing, high-performance computing systems, and

peripheral applications.

The IS41C8205 and IS41LV8205 are packaged in 28-pin

300-mil SOJ and 28-pin TSOP (Type II) with JEDEC

standard pinouts.
