    Abstract: A memory device includes rows and columns of memory cells, word lines each connected to a memory cell row, bit lines each connected to a memory cell column, a word line driver connected to the word lines, a bit line driver connected to the bit lines, word line switches each disposed on one of the word lines for selectively connecting one memory cell row to the word line driver, and bit line switches each disposed on one of the bit lines for selectively connecting one memory cell column to the bit line driver. A controller controls the word line switches to connect only some of the rows of memory cells to the word line driver at a first point in time, and controls the bit line switches to connect only some of the columns of memory cells to the bit line driver at a second point in time.

    Abstract: A memory device that generates a unique identifying number, and includes a plurality of memory cells and a controller. Each of the memory cells includes first and second regions formed in a semiconductor substrate, wherein a channel region of the substrate extends between the first and second regions, a floating gate disposed over and insulated from a first portion of the channel region, and a select gate disposed over and insulated from a second portion of the channel region. The controller is configured to apply one or more positive voltages to the first regions of the memory cells while the memory cells are in a subthreshold state for generating leakage current through each of the channel regions, measure the leakage currents, and generate a number based on the measured leakage currents.

    Abstract: A method of reading a memory device having a plurality of memory cells by, and a device configured for, reading a first memory cell of the plurality of memory cells to generate a first read current, reading a second memory cell of the plurality of memory cells to generate a second read current, applying a first offset value to the second read current, and then combining the first and second read currents to form a third read current, and then determining a program state using the third read current. Alternately, a first voltage is generated from the first read current, a second voltage is generated from the second read current, whereby the offset value is applied to the second voltage, wherein the first and second voltages are combined to form a third voltage, and then the program state is determined using the third voltage.
