DESCRIPTION
The ICSI 8513 Series is a 524,288 x 8-bit high-performance
CMOS Dynamic Random Access Memory. The Fast Page
Mode allows 1,024 random accesses within a single row with
access cycle time as short as 12 ns per 8-bit word.
These features make the 8513 Series ideally suited for high-
bandwidth graphics, digital signal processing, high-performance
computing systems, and peripheral applications.
The 8513 Series is packaged in a 28-pin 400mil SOJ and a 28
pin TSOP-2
