Abstract
A semiconductor storage apparatus of high convenience, which improves utilization efficiency of a memory region, is provided. A flash memory provided in the disclosure includes a memory controller and an NAND memory device. The memory controller includes an SRAM, an RRAM, and a write/selector. The SRAM stores a conversion table that converts a logical address into a physical address. The RRAM temporarily stores a small amount of data which should be programmed. The write/selector selectively writes the to-be-programmed data into the RRAM or an NAND memory unit of the NAND memory device.
