Abstract
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).
