    摘要: A method of performing a read operation from a first memory cell in a memory cell string that includes a first memory cell coupled to a second memory cell. The method includes providing a voltage to a first end of the first memory cell string that is closest to the first memory cell, providing a ground source to a second end of the first memory cell string that is opposite the first end, and determining whether a voltage change occurred at a node between the first and second memory cells in response to writing the first memory cell to a first state.

    摘要: A data storage device includes non-volatile memory; and a read circuit for performing multi-sample read operations on the memory during a normal mode of operation. The read circuit includes a digital counter having an output that indicates a single bit (e.g., a sign-bit). The read circuit allows an external device (e.g., a memory tester) to supply test clock pulses to an input of the digital counter during a test mode. The test clock pulses can be counted to determine a state of the digital counter.
