Abstract
The disclosure provides a semiconductor storage device and a reading method, which may achieve high-speed processing time for error detection and correction and achieve miniaturization. The flash memory of the disclosure has a NAND chip and an ECC chip. The NAND chip has: a memory array; a page buffer/sensing circuit, including latches Land L; and dedicated input and output terminals, which may be used for data transmission with ECC chip. The latch Lcontains cache Cand cache C, and the latch Lonly contains the cache C. The data in the cache Cof the latch Land the data in the cache Cof the latch Lare transmitted to the ECC chip. In response to outputting data at the initial address from the ECC chip, the next page is read from the memory array, and the read data is held in the latch L
