  • Publication number: 20230395138
    Abstract: Methods, devices, arrays and systems for reducing standby power for a floating body memory array. One method includes counting bits of data before data enters the array, wherein the counting includes counting at least one of: a total number of bits at state 1 and a total number of all bits; a total number of bits at state 0 and the total number of all bits; or the total number of bits at state 1 and the total number of bits at state 0. This method further includes detecting whether the total number of bits at state 1 is greater than the total number of bits at state 0; setting an inversion bit when the total number of bits at state 1 is greater than the total number of bits at state 0; and inverting contents of all the bits of data before writing the bits of data to the memory array when the inversion bit has been set.

  • Publication number: 20220359522
    Abstract: A semiconductor memory cell includes a floating body region configured to be charged to a level indicative of a state of the memory cell selected from at least first and second states. A first region of the memory cell is in electrical contact with the floating body region. A second region of the memory cell is spaced apart from the first region and is also in electrical contact with the floating body region. A gate is positioned between the first and second regions. A back-bias region is configured to generate impact ionization when the memory cell is in one of the first and second states, and the back-bias region is configured so as not to generate impact ionization when the memory cell is in the other of the first and second states.
