摘要： A timing generator which may be used for multiple-cycle controllers is disclosed. A Johnson counter which may have a selectively operable delay interposed between successive stages is utilized with an oscillator and a plurality of multiplexers to provide a plurality of timing pulse train cycles. Circuitry is provided to eliminate spurious output signals from the timing generator.

摘要： A system including first drivers (such as TTL drivers) operatively connected to the control lines of a volatile memory for providing control and refresh functions to the memory in a normal mode, and second drivers (such as CMOS drivers) operatively connected to the control lines for providing refresh functions to the memory in a standby mode. First and second power sources are provided for providing first and second voltage levels to the first and second drivers, respectively. A diode is connected between the first and second power sources to maintain the first and second voltage levels at a predetermined differential from each other in the event that the second power source fails to prevent damage to the second drivers (CMOS) through reverse biasing.

摘要： A first data set is written to first memory units identified as having a higher data reliability and a second data set is written to second memory units identified as having a lower data reliability than the first memory units. In some cases, the second data set may include metadata or redundancy information that is useful to aid in reading and/or decoding the first data set. The act of writing the second data set increases the data reliability of the first data set. The second data set may be a null pattern, such as all erased bits.
