  • Patent number: 11308999
    Abstract: The present disclosure describes various exemplary memory storage devices that can be programmed to bypass one or more memory cells in a bypass mode of operation. The various exemplary memory storage devices can adjust, for example, pull-up or pull-down, the electronic data as the electronic data passes through these exemplary memory storage devices in the bypass mode of operation. In some situations, the various exemplary memory storage devices may introduce an unwanted bias into the electronic data as the electronic data passes through these exemplary memory storage devices in the bypass mode of operation. The various exemplary memory storage devices can pull-down the electronic data and/or pull-up the electronic data as the electronic data is passing through these exemplary memory storage devices in the bypass mode of operation to compensate for this unwanted bias.
