发明名称 Semiconductor memory device with reduced package test time
摘要 A semiconductor memory device capable of performing a package test with bandwidth other than the default bandwidth without any wiring modification with respect to package option pads reduces package test time. The present invention implements the other package options based upon the wire bonding with an internal option. According to the operation mode, buffer control signals are used to control a VDD or VSS applied to the package option pads via the wire bonding. Buffer control signal are generated using a mode register reset. The buffer receiving the buffer control signal outputs the signal corresponding to the wiring state of the package option pad, blocks the signal path from the package option pads, and outputs a signal corresponding to a package option other than the default package option.
