Features:
◆
True Dual-Port memory cells which allow simultaneous
access of the same memory location
◆
High-speed data access
– Commercial: 3.6ns (166MHz)/4.2ns (133MHz) (max.)
– Industrial: 4.2ns (133MHz) (max.)
◆
Selectable Pipelined or Flow-Through output mode
◆
Counter enable and repeat features
◆
Dual chip enables allow for depth expansion without
additional logic
◆
Full synchronous operation on both ports
– 6ns cycle time, 166MHz operation (12Gbps bandwidth)
– Fast 3.6ns clock to data out
– 1.7ns setup to clock and 0.5ns hold on all control, data, and
address inputs @ 166MHz
