摘要： A method and system for multiple-bit programmable resistive cells having a multiple-bit programmable resistive element and using diode as program selector are disclosed. The first and second terminals of the diode having a first and second types of dopants can be fabricated from source/drain of MOS in a well for MOS devices or fabricated on the same polysilicon structure. If a multiple-bit programmable resistive cell has 2n (n>1) distinct resistance levels to store n-bit data, at least 2n−1 reference resistance levels can be designated to differential resistances between two adjacent states. Programming multiple-bit programmable resistive elements can start by applying a program pulse with initial program voltage (or current) and duration. A read verification cycle can follow to determine if the desirable resistance level is reached. If the desired resistance level has not been reached, additional program pulses can be applied.

摘要： A read-only memory (ROM) cell has first and second transistors connected in series between a true bit line and a voltage reference (e.g., ground), and third and fourth transistors connected in series between a complement bit line and the voltage reference. The gates of the first and third transistors are connected to a first word line, and the gates of the second and fourth transistors are connected to a second word line. The ROM cell is programmed to store any possible combination of two bits of information by appropriately (i) connecting the node between the first and second transistors to either the true bit line, the complement bit line, or the voltage reference and (ii) connecting the node between the third and fourth transistors to either the true bit line, the complement bit line, or the voltage reference.
