    摘要: A multi-level solid state non-volatile memory array has memory cells that store data using a first number of digital levels. A controller of the memory array encodes a series of data bits to generate a series of encoded data bits, and converts the series of encoded data bits into a series of data symbols. The controller sends, to the memory array, a stored series of data symbols based on the series of data symbols for storage in a memory cell of the multi-level solid state non-volatile memory array. The controller generates an output signal based on data associated with the stored series of data symbols. The output signal is characterized by a second number of digital levels greater than the first number of digital levels. The controller outputs a series of output data symbols based on the output signal.

    摘要: An apparatus, method, and system for removing glitches from a clock signal, including a duty cycle lock loop (DCLL) circuit. A glitch, which may produce errors in the clock signal, may occur when a read channel transitions from an acquired clock signal to an adjusted clock signal. In one embodiment of the inventive deglitch circuit, a first capacitor is charged and discharged in response to an input clock signal, and an output clock signal is provided depending upon the first capacitor's voltage. The output clock signal further charges and discharges a second capacitor whose ratio of charge to discharge currents provides a signal to bias the discharge current of the first capacitor. A second DCLL circuit may be provided to restore the output clock signal duty cycle to the original clock signal duty cycle.
