  • Patent number: 7028236
    Abstract: This invention provides a semiconductor memory test system in which the test system will not conduct logic comparison for a particular memory block after a failure is detected in the block. The test system which tests writing and erasing as a unit of block in the memory under test. The test system includes a register provided for each memory under test for holding a first failure generated in a particular block at a first control signal from a pattern generator, establishes a pass result for the particular block for test cycles after the first failure, thereby treating any failure result for the particular block as the pass result thereafter; and resets the register at a cycle specified by a second control signal from the pattern generator to release the pass result.

  • Patent number: 6019501
    Abstract: In an address generating device wherein addresses are generated by an address computation part in response to data and control signals read out of an instruction memory and are provided to a memory under test, a command control bit for storing a command control signal is provided in the instruction memory and a command register is provided for storing a command read out of a data area of the instruction memory. The output from the address computation part and the output from the command register are input into a first multiplexer, which selects either one of the two inputs in response to a command control signal read out of the command control bit. The output from the first multiplexer is applied to a descrambler, wherein it is translated to a physical address. A second multiplexer is provided for selecting either one of the outputs from the descrambler and the first multiplexer in such an instance.

  • Patent number: 5646948
    Abstract: A test data pattern, an address pattern, and a control signal are supplied from a pattern generator to a test memory. Data read from the test memory is compared with expected data by an XOR gate. When they match, a compared result that represents pass is output. When they mismatch, a compared result that represents fail is output. A match signal WC detected by the XOR gate is held in a register. The register outputs an inhibition signal to an inhibition gate of the test memory. Thus, a write enable signal WE is inhibited from being supplied to the test memory. In addition, the inhibition signal is supplied to a compared result inhibition gate. The compared result inhibition gate causes the compared result to be passed and prevents the test memory from being excessively written.
