Random access electrically programmable e-fuse ROM |
摘要 |
A one-time-programmable-read-only-memory (OTPROM) is implemented in a two-dimensional array of aggressively scaled suicide migratable e-fuses. Word line selection is performed by decoding logic operating at VDD while the bit line drive is switched between VDD and a higher voltage, Vp, for programming. The OTPROM is thus compatible with and can be integrated with other technologies without a cost adder and supports optimization of the high current path for minimal voltage drop during fuse programming. A differential sense amplifier with a programmable reference is used for improved sense margins and can support an entire bit line rather than sense amplifiers being provided for individual fuses.
