Abstract
Error correction systems and methods for improving sense matching conditions between hard-bit read (HBR) information and soft-bit read (SBR) information. For HBRs, a given set of sense conditions can include a discharged bit line of one or more cells that discharged during a previous HBR. For SBRs, a given set of sense conditions can include loading latches of the sense amplifiers for corresponding cells are with sense results of the previous SBR strobe when the corresponding cells discharged during a previous SBR strobe or loading the latches of the sense amplifiers with sense results of a previous HBR when the corresponding cells discharged during the previous HBR.
