Abstract

When using a microcontroller utilizing seven-bit instructions, the extra bit in program memory may be used to control a timing generator and a set of address counters in a memory tester. Fig. 1 shows a block diagram of an address/timing control circuit in a memory tester which controls a timing generator and provides addresses to a device under test (DUT). The address/timing control block requires two clock signals (clock 1 and clock 2) from a system clock and control logic and a specific instruction decode acknowledge CIDA) signal from the program and data memory.
