    摘要: A method for detecting word line leakage in a memory device includes coupling a first plurality of word lines in the memory device to a voltage source while grounding a second plurality of word lines. Each of the second plurality of word lines is adjacent to a corresponding one of the first plurality of word lines. The method includes waiting for a period of time to allow the word lines to reach a predetermined read voltage level. The method also includes decoupling the first plurality of word lines from the voltage source and waiting for a second predetermined period of time to allow the first plurality of word lines to discharge. The method further includes sensing a current associated with the word lines, and comparing the current with a predetermined reference current which is selected for identifying a word line leakage condition associated with the first plurality of word lines.

    摘要: Some embodiments of the present invention provide a memory device including a first memory array having a first word line and a comparator circuit having a first terminal coupled to a reference voltage and a second terminal coupled to a first switch selectively coupling the first word line to a power source or the second terminal. In an embodiment, the reference voltage is selected for identifying a leakage condition associated with the first word line. In another embodiment, the first switch is configured to couple the first word line to the power source for a first predetermined period of time to allow charging of the first word line. In another embodiment, the first switch is configured to couple the first word line to the second terminal of the comparator for at least a second predetermined period of time.

    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.
