ARCHITECTURE OF MEMORY CELL ARRAY, NON-VOLATILE MEMORY DEVICE HAVING THE SAME, AND METHOD OF CONSTRUCTING A MEMORY CELL ARRAY

摘要

A memory cell array, a non volatile memory device including the same, and a constructing method of a memory cell array are provided to improve a coupling property and to reduce a power noise. A memory bank has a plurality of logic sectors. A memory cell array is composed of a plurality of rows. A plurality of sub memory banks(B1L~B4L,B1R~B4R) has a plurality of physical sectors composed of the logic sectors. A plurality of sensing amplifier(SA1L~SA4L) is an exclusive sensing amplifier for each sub memory bank. The memory bank is formed by assembling the sub memory banks. A data recorded in the sub memory banks making a first memory bank is buffered by a different recording buffer in case a data is recorded in the first memory bank.
