Patent number: 11183257Abstract: The present application discloses a programmable memory, wherein an anti-fuse unit thereof is formed by adding an efuse between an anti-fuse programming transistor and a control transistor of a conventional anti-fuse unit such that the anti-fuse unit can be programmed twice, that is, normal programming can be implemented by breaking down a gate-source insulation layer of the anti-fuse programming transistor, and correction programming can be further implemented by fusing the efuse such that correction programming can be performed on a normal programming result, thereby changing a logical state of the normally programmed anti-fuse unit. For the programmable memory, a reprogramming method can be directly used to correct an error bit, thereby simplifying circuit and layout designs, resulting in a smaller layout area and higher reliability, increasing the applicability and flexibility, while retaining original features of reliable and safe data of the anti-fuse unit.Type: GrantFiled: November 19, 2020Date of Patent: November 23, 2021Assignee: Shanghai Huali Microelectronics CorporationInventors: Ying Yan, Jianming Jin
