Semiconductor storage device

Abstract

A semiconductor disk pack comprising a plurality of flash memories which operate slower in writing data thereinto than in reading data therefrom, a write buffer memory in which data are temporarily held, a processor which controls the data writing operation and which transfers and analyzes commands and statuses, an address controller which generates physical addresses, a circuit which generates a writing supply voltage Vpp for the flash memories, a memory address bus, and a data bus. The semiconductor disk pack is connected to a standard bus in a personal computer or the like. The processor writes the data of one word into a desired one of the flash memories, and it continuously writes the data of one word into an accessible one of the other flash memories during a latency which extends until the desired flash memory becomes capable of writing the next data of one word thereinto.
