  • Publication number: 20200005835
    Abstract: The present disclosure describes various exemplary memory storage devices that can be programmed to write electronic data into one or more memory cells in a write mode of operation and/or to read the electronic data from the one or more memory cells in a read mode of operation. The various exemplary memory storage devices can select various control lines to read the electronic data from the one or more memory cells onto data lines and/or to write the electronic data from these data lines into the one or more memory cells. In some situations, these data lines are charged, also referred to as pre-charged, to a first logical value, such as a logical one, before the various exemplary memory storage devices write the electronic data into the one or more memory cells. During this pre-charging of these data lines, the various exemplary memory storage devices electrically isolate these data lines from specialized circuitry within these exemplary memory storage devices.
