Abstract
Methods and non-volatile storage systems are provided for determining erratically programmed storage elements, including under-programmed and over-programmed storage elements. Techniques do not require any additional data latches. A set of data latches may be used to store program data for a given memory element. This program data may be maintained after the programming is over for use in erratic program detection. In one embodiment, lockout status is kept in a data latch that is used to serially receive program data to be programmed into the storage element. Therefore, no extra data latches are required to program the storage elements and to maintain the program data afterwards.
