DESCRIPTION
The ISSI IS41C4100 and IS41LV4100 are 1,048,576 x 4-bit
high-performance CMOS Dynamic Random Access
Memory. Both products offer accelerated cycle access
EDO Page Mode. EDO Page Mode allows 512 random
accesses within a single row with access cycle time as
short as 10ns per 4-bit word.
These features make the IS41C4100 and IS41LV4100 ideally
suited for high band-width graphics, digital signal processing,
high-performance computing systems, and peripheral applications.
The IS41C4100 and IS41LV4100 are available in a 20-pin,
300-mil SOJ package.
