Abstract
A preburn-in DRAM module circuit board is provided, which allows a plurality of DRAM modules to be constructed directly thereon, and which can be directly connected to a large burn-in oven so as to perform a burn-in process concurrently on the DRAM modules mounted thereon to check for any defected IC chips that are to be reworked. After the burn-in process, each of the DRAM modules can be cut apart from the circuit board to serve as a single memory module. The preburn-in DRAM module circuit board allows the manufacturing process for the DRAM modules to be reduced in schedule and manufacturing cost. Material cost can also be saved since the burn-in circuit and the module circuit are arranged on the same circuit board.
