    • An electronic device can include a first memory cell and a second memory cell. The first memory cell can include a first source, and a second memory cell can include a second source. The first memory cell and the second memory cell can lie within a same sector of a memory array. In one embodiment, erasing the electronic device can include erasing the first memory cell while inhibiting the erase of the second memory cell. A third memory cell can have a third source and lie within another sector. In another embodiment, inhibiting the erase of the first memory cell can include placing the first source and the third source at a same potential. In a particular embodiment, the first source can be electrically insulated from the second source.

    • A method for adjusting an operating parameter of an integrated circuit having a memory and logic, where the logic includes a timing circuit, includes accessing the memory, determining a relative speed of the memory access with respect to a speed of the timing circuit, and selectively adjusting the operating parameter based on the relative speed. In one embodiment, an integrated circuit may include a ring oscillator, a shift register having a clock input coupled to an output of the ring oscillator, and compare logic coupled to an output of the shift register. The shift register is enabled in response to initiating a memory access to a memory and disabled in response to completing the memory access. The compare logic provides a relative speed indicator representative of a relative speed of the memory.

    • A memory system (200) has an array of addressable storage elements (210) arranged in a plurality of rows and a plurality of columns, and decoding circuitry (220, 230) coupled to the array of addressable storage elements (210). The decoding circuitry (220, 230), in response to decoding a first address, accesses a first storage element of a first row of the plurality of rows, and, in response to decoding a second address consecutive to the first address, accesses a second storage element of a second row of the plurality of rows. The second row of the plurality of rows is different from the first row of the plurality of rows. By implementing a memory system wherein consecutive addresses correspond to storage elements of different rows, read disturb stresses along a single row can be minimized.

    • A method an apparatus for performing a reset operation in an integrated circuit where a memory programming voltage is recovered allowing use of the memory during reset. The voltage recovery unit includes a high voltage conversion portion active for a first recovery period, and a low voltage conversion portion active for a subsequent second recovery period, the low voltage conversion portion is inactive for the first recovery period. The first and second recovery portions are responsive to assertion of a reset signal and an intermediate reset signal generated before the end of the reset period. Recovery of the programming voltage allows uncorrupted retrieval and use of a configuration word during reset. The high voltage conversion portion includes p-channel devices with robust breakdown resistance, and the low voltage conversion portion includes n-channel devices which provides improved speed of operation.
