⢠Fully synchronous; all signals registered on positive
edge of system clock
⢠Internal pipelined operation; column address can
be changed every clock cycle
⢠Internal banks for hiding row access/precharge
⢠Programmable burst lengths: 1, 2, 4, 8, or full page
⢠Auto precharge, includes concurrent auto precharge
and auto refresh modes
⢠Self refresh mode (not available on AT devices)
⢠Auto refresh
â 64ms, 4096-cycle refresh (15.6µs/row; commer-
cial and industrial)
â 16ms, 4096-cycle refresh (3.9µs/row; automotive)
⢠LVTTL-compatible inputs and outputs
⢠Single 3.3V ±0.3V power supply
