    Abstract: Methods and circuits for performing high speed write (programming) operations in a dual-bit flash memory array. The method includes, for example, erasing a first and second bit of each cell in the array to a first state, programming the first bit of each cell in the array to a second state, and subsequently programming the second bit of one or more cells in the array to one of the first and second state according to the user's data, resulting in fast write (programming) of those second bits. In addition, the circuit includes, for example, a core cell array having dual-bit flash memory cells configured into a plurality of array portions. The circuit further includes a control circuit configured to selectively block erase one of the array portions, wherein in a first phase of the block erase both first and second bit locations of each dual-bit flash memory cell in the one array portion have sufficient charge removed therefrom to achieve a first state. The control circuit is further configured to, in a second phase of the block erase, supply charge to the first bit location of each dual-bit flash memory cell of the one array portion to enable subsequently fast-write of user's data to the second bit location.

    Abstract: Flash memory cells are presented which comprise a dielectric material formed above a substrate channel region, a charge trapping material formed over the dielectric material, and a control gate formed over the charge trapping material. The cell may be programmed by directing electrons from the control gate into the charge trapping material to raise the cell threshold voltage. The electrons may be directed from the control gate to the charge trapping material by coupling a substrate to a substrate voltage potential, and coupling the control gate to a gate voltage potential, where the gate voltage potential is lower than the substrate voltage potential. The cell may be erased by directing electrons from the charge trapping material into the control gate to lower a threshold voltage of the flash memory cell, such as by coupling the substrate to a substrate voltage potential, and coupling the control gate to a gate voltage potential, where the gate voltage potential is higher than the substrate voltage potential.

    Abstract: According to one exemplary embodiment, a programmable ROM array includes at least one bitline situated in a substrate. The programmable ROM array further includes at least one wordline situated over the at least one bitline. The programmable ROM array further includes a memory cell situated at an intersection of the at least one bitline and the at least one wordline, where the memory cell includes a dielectric region situated between the at least one bitline and the at least one wordline. A programming operation causes the memory cell to change from a first logic state to a second logic state by causing the dielectric region to break down. The programming operation causes the memory cell to operate as a diode. A resistance of the memory cell can be measured in a read operation to determine if the memory cell has the first or second logic state.
