Test pattern generating apparatus

摘要

A test pattern generating apparatus in which a microprogram describing a test pattern to be generated is read for interpretation and execution, address and data patterns are generated by arithmetic operations and a memory control signal is produced, the address and data patterns and the memory control signal being applied to a memory under test. The address pattern is provided to an area inversion control signal generation section to produce an inversion control signal corresponding to the address pattern, by which the data pattern may be inverted and then outputted.
