Abstract
Memory circuits that read the bit state of memory cells are disclosed. In some embodiments, a memory circuit, includes a memory cell configured to store a bit. A reference line is configured to receive a reference signal and a data line is configured to receive a data signal. The data line is configured to be selectively coupled to the memory cell. A charge voltage select unit is configured to charge the reference line and the data line in response to a select signal being in a first select state and discharge the reference line and the data line in response to the select signal being in a second select state. A sense amplifier is configured to compare the data signal and the reference signal to sense a bit state of the bit stored by the memory cell.
