Abstract:
A one-transistor (1T) one-time programmable (OTP) anti-fuse bitcell is provided. The 1T OTP anti-fuse bitcell includes a gate, a diffusion region including at least two sub-regions, and a gate oxide region located between the gate and the diffusion region, the gate oxide region including a thin gate oxide region and a thick gate oxide region.
Abstract:
Semiconductor fuse elements and method of producing the same are disclosed. A disclosed example multilayered die includes a transistor comprising a source, a drain and a gate, a metal interconnect extending through an interlayer dielectric, and a dielectric layer disposed between the metal interconnect and the drain to define a programmable fuse element.
Abstract:
An apparatus includes a multiple time programmable (MTP) memory device. The MTP memory device includes a metal gate, a substrate material, and an oxide structure between the metal gate and the substrate material. The oxide structure includes a hafnium oxide layer and a silicon dioxide layer. The hafnium oxide layer is in contact with the metal gate and in contact with the silicon dioxide layer. The silicon dioxide layer is in contact with the substrate material. The MTP device includes a transistor, and a non-volatile state of the MTP memory device is based on a threshold voltage of the transistor.
Abstract:
Provided is a method based on OTP memory. The method includes: according to OTP memory layout, getting rid of the floating gate (104) of the second MOS transistor of the OTP storage unit which is used for storage data "0",so as to converting the OTP storage unit into MROM storage unit for storage data "0"and remaining the original structure of the OTP storage unit which is used for storage data "1" in the OTP memory layout, the original structure of the OTP storage unit functions as MROM storage unit which is used for storage data "1", so as to producing the MROM memory layout and then making up MROM memory according to the MROM memory layout. The OTP memory layout regulated and determined the store data is changed into MROM memory layout. The process of OTP manufacture can be changed into process of MROM manufacture only by modifying one mask in the manufacture process. It saves device programming and testing time, saves costs, and simplifies the process.
