Method and apparatus for reduced power cell
View Patent ↗The invention relates to reduced power cells. Some embodiments of the invention provide a memory circuit that has a storage cell. The storage cell contains several electronic components and an input. The electronic components receive a reduced voltage from the input to the cell. The reduced voltage reduces the current leakage of the electronic components within the cell. Some embodiments provide a memory circuit that has a level converter. The level converter receives a reduced voltage and converts the reduced voltage into values that can be used to store and retrieve data with stability in the cell. Some embodiments provide a method for storing data in a memory circuit that has a storage cell. The method applies a reduced voltage to the input of the cell. The method level converts the reduced voltage. The reduced voltage is converted to a value that can be used to store and retrieve data with stability in the cell. The reduced voltage reduces a current leakage of electronic components within the cell.
1. An integrated circuit (IC) comprising:
a) a first circuit for operating at a first voltage;
b) a storage circuit for storing a value at a reduced second voltage;
c) an amplifier circuit coupled to the storage circuit (1) for receiving the stored value at the reduced second voltage, and (2) for producing a value at the first voltage to supply to the first circuit.
2. The IC of claim 1 , wherein the amplifier circuit comprises a first set of circuits that operate in response to a signal with the first voltage and a second set of circuits that operate in response to a signal with the second voltage.
3. The IC of claim 1 , wherein storing the value at the reduced second voltage reduces power usage of the IC.
4. The IC of claim 1 , wherein the storage circuit stores configuration data for configuring the first circuit during operation of the IC.
