    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).

    摘要: Techniques are disclosed herein for automatically self-disabling a memory die in the event that a programmable element on the memory die for indicating whether the memory die is defective cannot be trusted. Memory die are provided with chip enable circuitry to allow particular memory die to be disabled. If the programmable element can be trusted, the state of the programmable element is provided to the chip enable circuitry to enable/disable the memory die based on the state. However, if the programmable element cannot be trusted, then the chip enable circuitry may automatically disable the memory die. This provides a greater yield for multi-chip memory packages because packages having memory die with a programmable element that cannot be trusted can still be used.
