Abstract
A memory and a method for operating the memory having a sleep mode are provided. The memory one or more storage elements and a bitline coupled to the one or more storage elements. A precharge circuit is configured to precharge the bitline during a precharge period and float the bitline during a sleep mode. An operating circuit coupled to the one or more storage elements, wherein at least one of the operating circuit and the one or more storage elements being configured to remain electrically coupled to a supply voltage in the sleep mode.
Claims15
A memory, comprising:
- one or more storage elements;
- a bitline coupled to the one or more storage elements;
- a precharge circuit configured to precharge the bitline during a precharge period and float the bitline during a sleep mode;
- and
- an operating circuit coupled to the one or more storage elements, wherein at least one of the operating circuit and the one or more storage elements is configured to remain electrically coupled to a supply voltage in the sleep mode,
- wherein an initiation of the precharge period immediately follows an exiting of the sleep mode.
A method for operating a memory, comprising:
- precharging a bitline during a precharge period, the bitline being coupled to one or more storage elements;
- entering a sleep mode and floating the bitline in the sleep mode, wherein at least one of an operating circuit coupled to the one or more storage elements and the one or more storage elements remains electrically coupled to a supply voltage in the sleep mode;
- exiting the sleep mode;
- and
- initiating the precharge period immediately following the exiting of the sleep mode.
(canceled)
A memory, comprising:
- a bitline;
- means for storing one or more values, wherein the means for storing is coupled to the bitline;
- means for precharging the bitline during a precharge period and floating the bitline during a sleep mode;
- and
- means for operating the means for storing, wherein at least one of the means for operating and the means for storing being configured to remain electrically coupled to a supply voltage in the sleep mode.
