Abstract
The disclosure provides a semiconductor storage device and a reading method that can achieve high-speed processing of error detection and correction and miniaturization. The flash memory of the disclosure has a NAND chip and an ECC chip. The NAND chip includes a memory array, and a page buffer/sensing circuit including a latch (L) and a latch (L). The ECC chip includes RAM_E and RAM_O. The RAM_E and RAM_O hold the read data output from the latches (L, L) of the NAND chip. RAM_E holds the data of the even-numbered sectors, and RAM_O holds the data of the odd-numbered sectors. Making RAM_E or RAM_O alternately hold the data of the sectors can reduce the data size of RAM_E and RAM_O.
