Abstract
In a particular embodiment, a device includes a reference voltage circuit to generate a controlled voltage. The device includes a frequency circuit configured to generate a frequency output signal having a pre-set frequency and a counter to generate a count signal based on the pre-set frequency. The device also includes a delay circuit coupled to receive the count signal and to produce a delayed digital output signal and a latch to generate a pulse. The pulse has a first edge responsive to a write command and a trailing edge formed in response to the delayed digital output signal. In a particular embodiment, the pulse width of the pulse corresponds to an applied current level that exceeds a critical current to enable data to be written to an element of the memory but does not exceed a predetermined threshold.
