Semiconductor storage device

Abstract

The disclosure provides a semiconductor storage device, which can shorten the processing time for error detection and correction. The flash memory of the present disclosure has a NAND chip and an ECC chip. The NAND chip has dedicated input and output terminals which can transmit data with the ECC chip, and the ECC chip has a dedicated input and output terminal which can transmit data with the NAND chip. When reading in the NAND chip, the NAND chip transmits the read data containing the parity data to the ECC chip through the dedicated input and output terminals. The ECC chip detect and correct errors in the read data based on the parity data, and the corrected data is transmitted to the controller through the input and output terminals.

Dependencies are inferred from the claim text.
