Abstract

An integrated circuit, including but not limited to a memory device, receives an externally provided voltage signal and selectively adjusts the timing of internal control signals. An external signal selects between two possible pre-determined delay paths. The delay paths are adjusted using fuse circuitry which can be programmed by the manufacturer prior to implementation by a user. The delay path adjustment feature is particularly applicable to adjusting output signal timing to allow the integrated circuit to be operated in an environment which requires slower communications speeds. The same integrated circuit, therefore, can also be implemented in an environment which allows for faster communications speeds.
