Abstract:
1. A method of forming an embedded Multi-Time-Read-Only-Memory (eMTPROM) comprising: forming a Metal-Oxide-Semiconductor-Field-Effect-Transistor (MOSFET) array of cells having an initial threshold voltage (VT creating two dimensional meshed source line network (MSLN) respectively running in said first and second directions in a standby state, wherein said BLs and said MSLN are at a power supply voltage (VDD), and said WLs are at a ground voltage (GND); storing at least one data bit by selectively trapping charges in a dielectric of a target MOSFET, wherein said initial threshold voltage (VT reading a data bit by using said MOSFET threshold voltage having one of said VT resetting said data bit to a de-trapped state by de-trapping said charge.
