Abstract: A memory device comprises a memory cell and a sense amplifier which has a sensing interval. An output circuit is coupled to the sense amplifier and responsive to a clock signal to accept the signal from the sense amplifier. A first source of timing signals generates a first timing signal in response to an enable signal which is asynchronous relative to the clock signal. A second source of timing signals generates a second timing signal based on the clock signal. A switch selects one of the first and second timing signals at the timing signals for use to define pre-charge and sensing intervals for the sense amplifier. The first source of timing signals is selected during an interval of time corresponding to a clock latency, so that the timing signals define a sensing interval where transitions in the clock signal are outside of the sensing interval.

Abstract: A method of adjusting the write speed of a CD drive includes writing data from a CD drive to a disk at a first speed during a first preset time. If, at the end of the first preset time, the data error rate at the first speed is larger than the error allowance upper limit for the first preset time, then writing of the data will be completed at the first speed. However, if at the end of the first preset time, the data error rate at the first speed is smaller than the error allowance upper limit for the first preset time, then the writing speed will be adjusted to a second higher speed. The same process can be repeated for the second higher speed.
