摘要: A circuit is presented for determining whether or not to invert a bus, for example a data bus that is operable having multiple widths. The circuit includes comparison circuitry that can receive both the current and next values for the bus and individually compare the current and next values of the bits on the bus to determine whether these have changed. A voting circuit receives the result of these determinations and also receives an indication of width with which the bus is being operated. The voting circuit then determines a bus inversion values based upon whether the number of bits on the data that have changed exceed a value that depends upon the indication of bus width.

摘要: An apparatus and technique for testing of multi-level cells (MLC) in a memory storage device using a high bandwidth data path architecture. The technique includes hardware for obtaining a first data and a second data from a multilevel cell memory. The first data is different from the second data. The first data and second data are compared and, based at least in part on this comparison, the multilevel cell memory is programmed. Programming the multilevel cell memory includes accessing memory cells in the multilevel cell memory and determining the number of bits per memory cell of the first data that need programming.

摘要: A flash memory includes multi-level cells (MLC) that are programmed with a combination of coarse gate voltage steps and fine gate voltage steps. The multi-level cells include floating gate transistors that are programmed by modifying the threshold voltages of the floating gate transistors. Coarse gate voltage steps are used until the threshold voltage any of the transistors being programmed reaches a reference value, and fine steps are used thereafter.
