    摘要: Techniques are described herein for detecting and recovering over-erased memory cells in a flash memory device. In one embodiment, a flash memory device includes a memory array including a plurality of blocks of memory cells. The device also includes a command interface to receive a command from a source external to the memory device. The device also includes a controller including logic to perform a leakage-suppression process in response to the command. The leakage-suppression process includes performing a soft program operation to increase a threshold voltage of one or more over-erased memory cells in a given block of memory cells and establish an erased state.

    摘要: Techniques are described herein for detecting and recovering over-erased memory cells in a flash memory device. In one embodiment, a flash memory device is described including a memory array including a plurality of blocks of memory cells. The device also includes a controller to perform a leakage-suppression process. The leakage-suppression process includes determining that a given block of memory cells includes one or more over-erased memory cells. Upon the determination, the leakage-suppression process also includes performing a soft program operation to increase the threshold voltage of the over-erased memory cells in the given block.

    摘要: Various discussed approaches improve the over erase issue and the coupling effect, and include (A) multilevel contacts between (i) the first outer selected word line of an erase group, and (ii) the first unselected word line outside the ease group neighboring the first outer selected word line; (B) a sufficient separation distance between (i) the first outer selected word line of an erase group, and (ii) the first unselected word line outside the ease group neighboring the first outer selected word line. These are examples of electrically isolating (i) the first outer selected word line of an erase group, from (ii) the first unselected word line outside the ease group neighboring the first outer selected word line.

    摘要: A memory apparatus includes a host device and a slave device. The host device stores verification data. The slave device includes a memory unit, a control unit, and a logic unit. The control unit drives the memory unit to provide storage data in a data transmission sub-period, and further provides a control signal, indicating the first verification data, in a dummy sub-period. The logic unit provides first preamble data, indicating substantially a same data value as the verification data, in the dummy sub-period in response to the first control signal. The preamble data and the storage data are transmitted according to an internal clock signal. The host device samples the first preamble data according to an external clock signal, and determines whether the external and the internal clock signals are synchronized by comparing the first preamble data and the first verification data.
