    摘要: In a non-volatile memory, a selected page on a word line is successively programmed by a series of voltage pulses of a staircase waveform with verifications in between the pulses until the page is verified to a designated pattern. The programming voltage at the time the page is programmed verified will be to estimate the initial value of a starting programming voltage for the page. The estimation is further refined by using the estimate from a first pass in a second pass. Also, when the test is over multiple blocks, sampling of word lines based on similar geometrical locations of the blocks can yield a starting programming voltage optimized for faster programming pages.

    摘要: High performance non-volatile memory devices have the programming voltages trimmed for individual types of memory pages and word lines. A group of word lines within each erasable block of memory are tested in successive program loops to minimize the problem of incurring excessive number of erase/program cycles. An optimum programming voltage for a given type of memory pages is derived from statistical results of a sample of similar of memory pages.

    摘要: A memory card and methods for testing memory cards are disclosed herein. The memory card has a test interface that allows testing large numbers of memory cards together. Each memory card may have a serial data I/O contact and a test select contact. The memory cards may only send data via the serial data I/O contact when selected, which may allow many memory cards to be connected to the same serial data line during test. Moreover, existing test socket boards may be used without adding additional external circuitry. Thus, cost effective testing of memory cards is provided. In some embodiments, the test interface allows for a serial built in self test (BIST).
