Abstract: A self-test controller includes a memory configured to store a test patterns, configuration registers, and a memory data component. The test patterns are encoded in the memory using various techniques in order to save storage space. By using the configuration parameters, the memory data component is configured to decode the test patterns and perform multiple built-in self-test on a multitude of test cores. The described techniques allow for built-in self-test to be performed dynamically while utilizing less space in the memory.

Abstract: Disclosed are methods and apparatus for securely accessing and testing a double data rate (DDR) memory device. The apparatus includes a first memory test access port (TAP) configured to enable or disable access to at least one double date rate (DDR) memory device, a second memory TAP configured to enable or disable access to at least one non-DDR memory device, and a test controller configured to test the at least one DDR memory device via the first memory TAP or test the at least one non-DDR memory device via the second memory TAP. In an aspect, at least one non-DDR memory device contains proprietary information. Accordingly, access to the at least one non-DDR memory device via the second memory TAP is disabled when access to the at least one DDR memory device via the first memory TAP is enabled.
