An object of this invention is to provide a semiconductor memory device capable of increasing the read transfer rate by performing the read operation in parallel while suppressing the voltage drop when a large current is passed to a memory chain and reducing a chip area by reducing the number of peripheral circuits to feed power. A semiconductor memory device according to this invention includes upper and lower electrodes in a flat plate shape, first and second select transistors extending in first and second directions respectively, and a wire arranged between the first select transistor and the second select transistor and the wire and the lower electrode are configured to be electrically insulated from each other by turning off the first select transistor (see FIG. 2).
Abstract:
A semiconductor storage apparatus provides a large capacity phase-change memory possessing high speed operation, low electrical current, and high-reliability. During the period that a read-out start signal is activated in the memory region control circuit and the block of pairs of sense-latch and write driver is performing the verify read in the upper section memory region; the write enable signals in the memory region control circuit are activated and the block of pairs of sense-latch and write driver perform rewrite operation of the data in the lower section memory region. This type of operation allows cancelling out the time required for the verify read and the time required for the time-division write operation by performing the verify read in one memory region, while performing time-division rewrite in other memory region, to achieve both higher reliability rewrite operation along with suppressing the rewrite operation peak electrical current.
