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.
Claims20
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.
A single-byte data write method of a memory device, comprising:
- receiving a byte of a program data through a write circuit;
- reading a plurality of bytes of a array data stored by a memory array according to a memory address corresponding to the program data through a sense amplifier and a Y decoder and writing the array data to a page buffer through the write circuit and the Y decoder;
- writing the program data to the memory array through the write circuit and the Y decoder;
- and
- writing the array data to the memory array through the page buffer.
