A logic circuit and operation method based on nor flash array

Abstract

The invention discloses a logic circuit and an operation method based on a NOR flash array. The logic circuit includes a NOR flash array and peripheral circuits; the NOR flash array is used to realize operations and store operation results, and the peripheral circuits are used to transmit data and control signals, thereby Control the operation and storage process of NOR flash array. By writing different logic signals into the NOR flash device, applying different voltages on the bit line, word line and source line, and finally reading the charge state in the floating gate layer of the NOR flash device, logic operations with different functions are realized. The logic circuit and operation method based on the NOR flash array provided by the present invention can realize the integration of storage and calculation in the NOR Flash array, and perform storage and calculation at the same time, which can greatly reduce the time and energy consumed when the calculation data is transmitted between the calculation unit and the storage unit .

Description

technical field [0001] The invention belongs to the field of microelectronic devices, and more specifically relates to a logic circuit and an operation method based on a NOR flash array. Background technique [0002] In the history of computer development, people have always required computers to be faster and more powerful. With the advent of the era of big data, Moore's Law of integrated circuits that improves computing performance by scaling down the size of nano-transistor logic devices has become difficult to continue. The bottleneck problem of separation of storage and computing in the traditional von Neumann computing architecture has become prominent. The existing architecture and Hardware cannot meet the demand for super computing power from the explosive growth of information. In the research of new computer architecture, the computing architecture based on the fusion of computing and storage based on non-volatile memory is a very promising research idea. [0003...
