    摘要: A system for testing a device under test (DUT) includes a test controller unit that includes a first memory operable to store a data pattern; a bridge circuit that includes a second memory that is smaller than the first memory, and a functional unit that includes a third memory that is smaller than the second memory. Portions of the data pattern are selectively transferred from the first memory to the second memory during and for DUT testing operations. The functional circuit interfaces with the DUT for testing. Portions of the data pattern are selectively transferred from the second memory to the third memory for application to the DUT.

    摘要: The invention relates to a method for detecting a subroutine call stack modification, including the steps of, when calling a subroutine, placing a return address at the top of the stack; at the end of the subroutine, using the address at the top of the stack as the return address, and removing the address from the stack; when calling the subroutine, accumulating the return address in a memory location with a first operation; at the end of the subroutine, accumulating the address from the top of the stack in the memory location with a second operation, reciprocal of the first operation; and detecting a change when the content of the memory location is different from its initial value.

    摘要: Apparatuses and methods for compressing data responsive to a plurality of memory accesses is described. An example compression circuit includes a comparator configured to compare data provided by a group of memory cells associated with a repair address. Each subset of one or more bits of the data is sequentially provided by the group of memory cells responsive to a respective memory access of a plurality of memory accesses. The example compression circuit further including an error bit latch coupled to the comparison circuit. The error bit latch configured to, responsive to an output received from the comparison circuit indicating an error, compress the data to an error bit by setting the error bit to an error detected state and latching the error bit having the error detected state.

    摘要: An automatic test equipment includes a test apparatus, a first control device, a first assisting device, and a second control device. The test apparatus is applied for testing a first object, wherein the test apparatus has a first cover. The first control device has an activating device. The first assisting device is electrically connected to the first control device. The second control device is electrically connected to the first control device and the test apparatus. When the activating device is activated, the first control device controls the first assisting device to lower the first cover and then the first control device transmits a first control signal to the second control device for allowing the test apparatus to test the first object.
