Abstract: Methods and apparatuses for adjusting trim settings for internally generated voltages of an integrated circuit device are provided. In one embodiment the apparatus receives a target digital value for an internally generated voltage, and compares the target digital value to a current digital value for the internally generated voltage. If the comparison indicates that a difference between the target digital value and the current digital value is greater than an allowable threshold, a trim setting used to trim the internally generated voltage is adjusted based on the difference. The trim setting may be adjusted until the difference between the target digital value and the current digital value is less than or equal to the allowable threshold.

Abstract: The present invention relates to a memory system including an external clock and a memory chip connected to the external clock. The external clock generates an operating signal at an operating frequency that controls at least one electrical component of the memory system. The memory chip includes a frequency detector that detects at least a range of frequency values for the operating frequency. Further, the frequency detector includes a reference frequency generator that generates a reference signal at a reference frequency.
