RECONFIGURABLE SERIAL SIGNAL GENERATOR IN MEMORY MODULE TESTER

摘要

PURPOSE: A memory module test apparatus of a serial signal generator is provided to test a memory module which have various SPD(Serial Presence Detect) performance characteristic by resetting a test signal property in response to the operation characteristic of a SPD device. CONSTITUTION: A serial clock generating part(145) generates a serial clock signal of a SPD device and a reset signal in response to an internal clock signal. A timing reset part(146) gets a plurality of delay clock signals which have different delay property by delaying the internal clock signal after being enabled in response to the reset signal. A timing reset part selects one among a plurality of delay clock signals obtaining in response to the timing reset value. The timing reset part outputs a selected signal to the resetting clock signal. A serial data generating part generates serial data of a SPD device in which the timing is reset from the edge of the serial clock signal after receiving a resetting clock signal.
