Abstract:
A semiconductor memory device includes a first memory cell array having a first plane which is composed of a plurality of blocks each having a plurality of memory cells, a sense circuit which reads data the memory cells, a sequencer which receives control signals from outside, a first address register, and a second address register which receives an output address from the first address register and outputs an address signal in response to an address control signal from the sequencer. In reading from the memory cells, the sequencer reads a page n in accordance with the address stored in the second address register, then transfers an address stored in the first address register to the second address register concurrently with outputting data read from the page n to outside and reads data from an arbitrary page m in accordance with the address transferred to the second address register.
