MEMORY BLOCK AND SEMICONDUCTOR STORAGE DEVICE USING THE MEMORY BLOCK

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor storage device in which memory capacity can be increased without deteriorating an operation speed and which is suitable to mixed loading with logic. SOLUTION: This semiconductor storage device has a memory block which has data input-output circuits that are arranged in accordance with a memory cell arrays and arranged in the order of data transfer and control circuits arranged in the order of a critical path from an input buffer up to a row decoder and can independently operate, and a control circuit in which a plurality of the memory blocks are adjacently arranged and which branches an external control signal and an external address signal within the memory blocks and has a function for controlling the operation of each memory block.
