Page 1
... Mode allows 1,024 random accesses within a single row with access cycle time as short 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 high- bandwidth graphics, digital signal processing, high-performance computing systems, and peripheral applications ...

... OE and WE and RAS). LCAS controls I/O0 through I/O7 and UCAS controls I/O8 through I/O15. The IS41LV16105B CAS function is determined by the first CAS (LCAS or UCAS) transitioning LOW and the last transitioning back HIGH. The two CAS controls give the IS41LV16105B both BYTE READ and BYTE WRITE cycle capabilities ...
