    Abstract: A neural network device with synapses having memory cells each having a floating gate and a first gate over first and second portions of a channel region, and second and third gates over the floating gate and over the source region. First lines each electrically connect the first gates in one of the memory cell rows, second lines each electrically connect the second gates in one of the memory cell rows, third lines each electrically connect the third gates in one of the memory cell rows, fourth lines each electrically connect the source regions in one of the memory cell rows, and fifth lines each electrically connect the drain regions in one of the memory cell columns. The synapses receive a first plurality of inputs as electrical voltages on the first, second or third lines, and provide a first plurality of outputs as electrical currents on the fifth lines.

    Abstract: A memory device including a silicon substrate having a planar upper surface in a memory cell area and an upwardly extending silicon fin in a logic device area. The silicon fin includes side surfaces extending up and terminating at a top surface. The logic device includes spaced apart source and drain regions with a channel region extending there between (along the top surface and the side surfaces), and a conductive logic gate disposed over the top surface and laterally adjacent to the side surfaces. The memory cell includes spaced apart source and drain regions with a second channel region extending there between, a conductive floating gate disposed over one portion of the second channel region, a conductive word line gate disposed over another portion of the second channel region, a conductive control gate disposed over the floating gate, and a conductive erase gate disposed over the source region.

    Abstract: The present invention relates to a flash memory cell with only four terminals and decoder circuitry for operating an array of such flash memory cells. The invention allows for fewer terminals for each flash memory cell compared to the prior art, which results in a simplification of the decoder circuitry and overall die space required per flash memory cells. The invention also provides for the use of high voltages on one or more of the four terminals to allow for read, erase, and programming operations despite the lower number of terminals compared to prior art flash memory cells.
