The invention discloses a simplified storage method for a one-time programmable memory. Control enabling input signals, address bus input signals and data bus input signals are subjected to multivalued logic conversion and combined logic, corresponding output enabling signals, programmable starting signals, data input signals and address selection signals are output to the one-time programmable memory, the one-time programmable memory realizes mode selection by identifying the input signals, and corresponding operations are completed by the one-time programmable memory under a determined mode state. According to the simplified storage method, the storage speed and the storage efficiency of the one-time programmable memory can be improved, the complexity of the input signals of the one-time programmable memory is simplified, the crosstalk in a programming process of the one-time programmable memory is reduced, the programming misoperation is avoided, the reliability of the one-time programmable memory is improved, the power consumption is reduced, and the integration and the application of the one-time programmable memory are facilitated. The one-time programmable memory is reasonable in structure, wide in application range and simple in implementing method, and is suitable for a semiconductor integrated circuit and a discrete component.

Description

technical field [0001] The invention relates to a simplified storage method applied to a one-time programming memory (OTP), which belongs to the technical field of integrated circuits. Background technique [0002] With the development of system on chip (SOC, System on Chip), memory, as the main medium of data exchange and information storage, has an increasing proportion in SOC chip design, and the SOC chip structure has higher and higher requirements for memory. It is required to have fast programming, low power consumption, high reliability and a more compact storage array structure, while requiring faster reading speed. [0003] As a highly reliable and inexpensive non-volatile memory, OTP memory is widely used in embedded systems, key storage and other fields. OTP memory can not only provide low-power performance, but also meet the requirements of non-volatile memory. In many applications, the non-volatile memory required by the device does not require hundreds or tho...
