Semiconductor storage device

Abstract

Abstract PURPOSE:To hold the continuity of a sequential lead by comparing always a sequential address and a random address and executing a writing to a memory only when the designated addresses of the addresses coincide and an external writing instruction is inputted. CONSTITUTION:An address comparing means 19 to compare a sequential address SA and a random address RA and to output the coincidence data of the addresses is provided. The sequential address SA and the random address RA are always compared and when the designated addresses of the addresses coincide and an external writing instruction, the inverse of We is inputted, a writing instruction, the inverse of WE3 is supplied to a RAM 13 to execute the sequential lead. Thus, even when a random writing instruction by the demand of a system is generated in the RAM to execute the sequential lead, the continuity of the sequential lead can be held.
