Embedded memory with configurable bit width

Abstract

The invention relates to an integrated circuit storage system, and particularly relates to an embedded memory with a configurable bit width. The memory comprises a first memory array, a second memory array, a third memory array, a fourth memory array, a read-write interface module which is connected with each of the four memory arrays, a bit width multi-path selector connected with the read-write interface module, an input-output module connected with the bit width multi-path selector, and four read-write control and decoding modules. According to the embedded memory, the memory array is divided into four parts, so that the word line and bit line length of a single memory array can be reduced, the read-write speed of a mass embedded memory can be increased, and meanwhile, bit width configuration can be supported flexibly, hardware cost of a product cannot be excessively increased, and the performance of the memory cannot be influenced.

Description

technical field [0001] The invention relates to an integrated circuit storage system, more specifically an embedded memory with configurable bit width. Background technique [0002] Embedded memory is a circuit module widely used in electronic systems, mainly used for large-scale data storage and exchange. With the advancement of the information age, the functional requirements of embedded systems have become complex and changeable, and the relatively single functional mode has long been unable to meet the needs of practical applications. , optional FIFO, optional internal detection and verification, etc. Introducing the IP hard core of block memory in the embedded system can solve the performance and function limitations of the logic resources in the embedded system, so that the embedded system can better support the large-scale, high-speed and low-power requirements in digital circuit design. consumption requirements. Although embedded memory has long been used in digit...
