Programmable burst lengths: 1, 2, 4, 8, or full page
Auto precharge, includes concurrent auto precharge,
and auto refresh modes
Self refresh mode; standard and low power
64ms, 4,096-cycle refresh (15.6s/row)
LVTTL-compatible inputs and outputs
Low voltage power supply
Partial-array self refresh (PASR) power-saving mode
