Memory device, peripheral circuit thereof and single-byte data write method thereof
First Claim
1. A peripheral circuit of a memory device, comprising:
- a Y decoder, coupled to a memory array of the memory device;
a page buffer, coupled to the memory array and the Y decoder;
a write circuit, coupled to the memory array and the page buffer through the Y decoder and receiving a byte of a program data; and
a sense amplifier coupled between the Y decoder and the write circuit, reading a plurality of bytes of a array data stored by the memory array through the Y decoder to provide the read array data to the write circuit;
wherein the read array data is based on a memory address corresponding to the program data, the read array data is written to the page buffer through the Y decoder, the program data is written to the memory array through the write circuit and the Y decoder, and the array data is written to the memory array by the page buffer.

Abstract
A memory device, a peripheral circuit thereof and a single-byte data write method thereof are provided. The peripheral circuit includes a Y decoder, a page buffer, and a write circuit. The write circuit is coupled to a memory array and the page buffer through the Y decoder and receives a byte of program data. The write circuit is based on a memory address corresponding to the program data to receive a plurality of bytes of array data stored in the memory array through the Y decoder, and the read array data is written to page buffer through the Y decoder. Next, the program data is written to the memory array through the write circuit and Y decoder, and the array data is written to the memory array by the page buffer.
