MEMORY SYSTEM WITH AN ARITHMETIC OPERATION CIRCUIT AND A PATTERN DETECTOR

摘要

Memory systems (155) include an array of storage cells (159) arranged in a row and column arrangement. A plurality of data write lines (320) coupled to the array are configured to supply data into a selected row of the array. A plurality of data read lines (325, 330) coupled to the array are configured to receive data from a selected column of the array in a single read operation. An arithmetic operation circuit (310) coupled to the plurality of data read lines is configured to generate a result value (355) based on data read from the storage cells of a selected column of the array. Methods of detecting a pattern, such as a color code pattern, are also provided.
