Abstract
A semiconductor memory device includes: a memory cell for storing data; a page buffer connected to the memory cell through a bit line, to store data in the memory cell or read data from the memory cell; and a cache latch connected to the page buffer through a bus node. When bit data transmission operation between the page buffer and the cache latch is performed, the bus node is discharged before starting the bit data transmission operation.
