Data processing system, operating method thereof, and computing system using the same

Abstract

A data processing system may include: a controller configured to receive a neural network processing request from a host device; a processing memory including: one or more sub arrays each including memory cells coupled between row lines and column lines; multiplexers (MUXs) provided for respective column line groups, which are configured by grouping the column lines by a preset number; and analog-to-digital converters (ADCs) coupled to the respective MUXs; and a deserializer. The deserializer is configured to receive, from the controller, data to be stored in a selected sub array and a first column address at which the data is to be stored, and remap the first column address to a second column address such that the data is distributed and stored in the memory cells coupled to the column line groups, in order to store the data in the sub array.
