Embodiment Construction

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0035] The invention provides a circuit and a method for adjusting and storing adjustment data of an electrical device to deal with device mismatch and program change.

[0036] Electrical fuses are commonly used in today's semiconductors for final conditioning and repair of packaged chips. Electrical fuses are designed to blow when the current flowing through the fuse exceeds a threshold, thereby causing an increase in energy and blowing the fuse. Electrical fuses provide non-volatile data storage by blowing the fuse during programming. The implementation of electrical fuses allows for more design flexibility, such as disposing fuses in the chip. Electrical fuses are ideal components for high-density memory devices because the wires allow place...

Abstract

The invention provides a device adjustment circuit and a fuse reference resistance adjustment circuit and an electrical device adjustment method. The device adjustment circuit includes: at least one reference device, at least one adjustment device, and at least one electric fuse basic control unit. The reference device has reference electrical parameters. The adjustment device is coupled to the reference device to form an adjustment reference device, and the adjustment reference device provides modified reference electrical parameters according to the reference device and the adjustment device. The electric fuse basic control unit controls whether the adjusting device is coupled to the reference device according to the state of the electric fuse. The device adjustment circuit provided by the present invention is used to deal with device mismatch and program change.

Description

technical field [0001] The present invention relates to an integrated circuit, and more particularly to a method of storing data with electrical fuses for adjusting device mismatch and program variation. Background technique [0002] Adjustment for device mismatch or adjustment for program changes is generally helpful in designing analog or logic circuits of a logic nature, such as sense amplifiers. The traditional method is to adjust the demand without retaining the adjustment data, or store the adjustment data in non-volatile devices, such as flash memory, electronically erasable programmable read-only memory (Electrically Erasable Programmable Read-Only Memory, EEPROM), Or the programmable read-only memory (Erasable Programmable Read-Only Memory, EPROM) can be eliminated. [0003] Assuming the adjustment data is not stored or generated on demand, it can consume a lot of time and energy. Data can be stored in non-volatile devices such as flash memory or EEPROM, but they ...
