Abstract
Power consumption of a serial EEPROM is reduced while simultaneously precluding data corruption during write operations. These results are achieved by operat- ing a brownout detector in the device to sense EE- PROM supply voltage below a predetermined level and thereupon to place the EEPROM in a reduced power mode, but only during an interval that a write sequence is taking place. Such an interval includes loading of data in a temporary storage cache and writing the loaded data into the EEPROM. At the same time that the low voltage level is detected during a write sequence, any load or write operation then in progress is aborted. The brownout detector is intentionally left disabled or in a sleep mode during any read mode or standby mode since there is no jeopardy of corrupting the EEPROM memory during those times.
