STATIC MEMORY APPARATUS AND DATA READING METHOD THEREOF

摘要

A static memory apparatus and a data reading method thereof are provided. The static memory apparatus includes a plurality of memory cells, a plurality of dummy memory cells, a sense amplifier, and a discharge current adjuster. The dummy memory cells respectively include a plurality discharge ends for discharging charges on a dummy bit line. The sense amplifier is enabled for a sensing and amplifying operation according to a signal on the dummy bit line, and the sense amplifier generates readout data accordingly. The discharge current adjuster adjusts at least one discharge current on at least one controlled discharge end according to an operating voltage of the memory cells.
