Title: Apparatus and method for test time reduction in a dynamic random access memory
Inventor: HASHIMOTO MASASHI
IPC: G11C29/00
Filed: 1997-03-11
Granted: 1999-09-21
Abstract: In a dynamic random access memory device, the time required for implementation of memory cell data retention time testing procedures can be reduced by changing the voltage level(s) applied to the components 13, 14 of the storage cell when compared to the voltages applied during the typical memory cell operation. By changing the voltage(s) applied to the components 13, 14, the difference in the bitlines 1, 2 detected by the sense amplifier 9 will be reduced. Because to the reduced bitline voltage difference, the decay of the charge on the storage cell causes a reduction in the data retention time. The data retention time is reduced in manner related to the typical memory cell operation. The altered voltage(s) can be applied to the storage cell bitlines 1, 2 and/or to the storage cell dummy capacitances.
