Abstract
A data buffer comprises data storage circuitry; input circuitry to input data to be stored by the data storage circuitry at a first operating voltage; output circuitry to output stored data from the data storage circuitry at a second operating voltage different to the first operating voltage; and control circuitry to control an operating voltage of the data storage circuitry to be substantially the first operating voltage during a data input operation by the input circuitry and to be substantially the second operating voltage during a data output operation by the output circuitry.
Claims21
A data buffer comprising:
- data storage circuitry;
- input circuitry to input data to be stored by the data storage circuitry at a first operating voltage;
- output circuitry to output stored data from the data storage circuitry at a second operating voltage different to the first operating voltage;
- and
- control circuitry to control an operating voltage of the data storage circuitry to be substantially the first operating voltage during a data input operation by the input circuitry and to be substantially the second operating voltage during a data output operation by the output circuitry.
A data buffer comprising:
- means for storing data;
- input means for inputting data to be stored by the data storing means at a first operating voltage;
- output means for outputting stored data from the data storing means at a second operating voltage different to the first operating voltage;
- and
- control means for controlling an operating voltage of the data storing means to be substantially the first operating voltage during a data input operation by the input means and to be substantially the second operating voltage during a data output operation by the output means.
A method of operation of a data buffer comprising:
- inputting data to be stored at a first operating voltage;
- storing the data in data storage circuitry;
- outputting stored data at a second operating voltage different to the first operating voltage;
- and
- controlling an operating voltage of the data storage circuitry to be substantially the first operating voltage during the inputting step and to be substantially the second operating voltage during the outputting step.
