  • Program memory test access collar
    Patent number: 7890804
    Abstract: A memory access device includes logic to switch data from a processor memory bus to a memory bus in a first operational mode, and to switch data from a test bus to the memory bus in a second operational mode, and logic to switch address signals from the processor memory bus to the memory bus in the first operational mode. In the second operational mode the device accepts from the test bus a starting memory address for memory reads and writes, and automatically and independently of the test bus adjusts a memory address for reads and writes during burst memory operations.
    Type: Grant
