Dynamic trim selection based on operating voltage levels for semiconductor devices and associated methods and systems

Abstract:

Dynamic trim selection based on operating voltage levels for semiconductor devices and associated methods and systems are disclosed. Certain semiconductor devices are expected to operate under two or more operating voltage levels. In some embodiments, the semiconductor device can be characterized to determine optimum timing and/or voltage conditions across multiple operating voltage levels. Consequently, multiple sets of timing and/or voltage conditions can be identified depending on the operating voltage levels, which can be stored in a non-volatile memory (NVM) array of the semiconductor device. During operation, the semiconductor device can determine the operating voltage level currently supplied to the semiconductor device and select one of the timing and/or voltage conditions stored in the NVM array such that the semiconductor device can operate with the optimum timing and/or voltage conditions that has been predetermined for the semiconductor device operating under the operating voltage level.
