com 256K x 16 (4-MBIT) DYNAMIC RAM WITH FAST PAGE MODE FEATURES • • • • • • • DESCRIPTION • • The ICSI IC41C16257 and the IC41LV16257 are 262,144 Fast access and cycle time x 16-bit high-performance CMOS Dynamic Random Access TTL compatible inputs and outputs Memory.
Fast Page Mode allows 512 random accesses Refresh Interval: 512 cycles/8 ms 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 Refresh Mode: RAS-Only, CAS-before-RAS byte, makes these devices ideal for use in 16-, 32-bit wide (CBR), Hidden data bus systems.
Self Refresh Mode: 512 cycles/64 ms (S version These features make the IC41C16257 and the IC41LV16257 only) ideally suited for high band-width graphics, digital signal JEDEC standard pinout processing, high-performance computing systems, and peripheral applications.
Single power supply: — 5V ± 10% (IC41C16257) The IC41C16257 and the IC41LV16257 are packaged in a 40-pin, 400mil SOJ and TSOP-2.
