Abstract
A 4-Mb DRAM that has 38-ns RAS (row-address-strobe) access time and a battery-backup (BBU) mode, and retains data with a 44-μA current requirement is described. The BBU mode is a self-refresh mode. Its power dissipation, however, is reduced in comparison with that of a normal refresh operation. The memory can operate as a standard 4-Mb DRAM, without any timing constraint on CAS (column-address-strobe) and RAS, if the operating cycle does not exceed 16 ms. This approach promises more stable supply at lower cost than specially provided counterparts such as pseudo-SRAMs.
