com ISSI APRIL 2005 ® DESCRIPTION The ISSI IS41LV16105B is 1,048,576 x 16-bit high-performance CMOS Dynamic Random Access Memories.
Fast Page Mode allows 1,024 random accesses within a single row with access cycle time as short as 20 ns per 16-bit word.
The Byte Write control, of upper and lower byte, makes the IS41LV16105B ideal for use in 16-, 32-bit wide data bus systems.
These features make the IS41LV16105B ideally suited for highbandwidth graphics, digital signal processing, high-performance computing systems, and peripheral applications.
The IS41LV16105B is packaged in a 42-pin 400-mil SOJ and 400-mil 44- (50-) pin TSOP (Type II).
