    摘要: A memory having a memory array having bit cells coupled to bit lines. The memory further includes a precharge circuit that precharges bit lines. The memory also includes a control circuit coupled to the precharge circuit that enables the precharge circuit at a beginning portion of a read cycle, keeps the precharge circuit disabled until an end of the read cycle, and keeps the precharge circuit disabled during a write cycle. A method of operating a memory, in which the memory includes an array of memory cells coupled to bit lines, includes precharging the bit lines at a beginning of a read cycle. The method also includes blocking precharging of the bit lines for a duration of a write cycle.

    摘要: A memory has bits that fail as power supply voltage is reduced to reduce power and/or increase endurance. The bits become properly functional when the power supply voltage is increased back to its original value. With the reduced voltage, portions of the memory that include non-functional bits are not used. Much of the memory may remain functional and use is retained. When the voltage is increased, the portions of the memory that were not used because of being non-functional due to the reduced power supply voltage may then be used again. This is particularly useful in a cache where the decrease in available memory due to power supply voltage reduction can be implemented as a reduction in the number of ways. Thus, for example an eight way cache can simply be reduced to a four way cache when the power is being reduced or endurance increased.

    摘要: A memory includes a memory array having a plurality of word lines, a plurality of latching predecoders, and word line driver logic. Each latching predecoder receives a clock signal and a plurality of address signals and latches a result of a logic function of the plurality of address signals in response to a first edge of a clock cycle of the clock signal and provides a predetermined value in response to a second edge of the first clock cycle of the clock signal, wherein, in response to the second edge, every latching decoder of the plurality of latching predecoders provides a same predetermined value. The word line driver logic selectively activates a selected word line of the plurality of word lines in response to the latched results.

    摘要: A method for dynamically controlling sense amplifier differential margin of a memory during operation, in an integrated circuit, comprising a plurality of addressable units, is provided. The method includes setting the sense amplifier differential margin corresponding to the plurality of addressable units to a first value. The method further includes if a read data error occurs when data is read from a set of the plurality of addressable units, then setting the sense amplifier differential margin corresponding to the plurality of addressable units to a second value, wherein the second value is greater than the first value.
