SEMICONDUCTOR MEMORY

摘要

PROBLEM TO BE SOLVED: To provide a flash memory capable of increasing an operational speed in a burst read-out mode without improving the performance of a transistor. SOLUTION: This semiconductor memory which is furnished with a function of a continuous read-out operation of data by synchronizing with a clock, includes; a memory array consisting of a memory element and a redundant memory element; a burst counter setting an upper-order address to a memory address and a lower-order address to a burst address to output them with the clock synchronization; a sense amplifier for outputting the data of the memory element selected by the memory address; a decoder for decoding the burst address; an address latch for synchronizing the burst address with the clock for storage; a page selector for selecting the data input in accordance with the burst address of the address latch; a redundancy replacement circuit for replacing the data with the redundancy data when the memory element is defective; and an output latch for outputting the data with the clock synchronization.
