Abstract
In semiconductor memory cells of the type including flip flop circuits in each cell and two sense output lines for determining the binary bits stored in the cell, an attempt to read data stored in the cell after a previous operation, before the sense lines have been fully restored to their quiescent state can result in the loss of data. This invention provides a means for restoring the sense lines very rapidly after an operation so that loss of data is prevented and the memory may be accessed at a higher frequency.
