Abstract:
A semiconductor memory device (and control method therefor) includes a plurality of word lines, a plurality of bit lines, a plurality of memory cells arranged at intersections of the word lines and the bit lines, a word driver that selects any one of the word lines, a plurality of sense amplifiers connectable to any of the bit lines, a sense-amplifier starting circuit that sequentially starts the sense amplifiers in response to a request of consecutive read operations to the memory cells connected to a predetermined word line, in a state that the predetermined word line is selected by the word driver, and an address determining circuit that temporarily stops an operation of the sense-amplifier starting circuit in response to a request of consecutive read operations to a same memory cell connected to a predetermined word line, in a state that the predetermined word line is selected by the word driver.
