Abstract
A system includes a processor and a flash memory block that may receive an operating voltage sufficient for reading a memory cell. A standby oscillator may generate a first signal to a Power-Supply-In-Package block and a second, higher frequency signal to a regulator block. The first signal may control the time at which charge is stored on a first capacitor that may be used to provide charge in a standby mode to a second capacitor. The second signal may control the time at which charge is stored on the second capacitor.
Claims21
A system, comprising:
- a processor;
- a device coupled to the processor that includes,
- a power-supply-in-package (PSIP) coupled to receive an input voltage potential and generate a supply voltage,
- a regulator coupled to the PSIP to receive the supply voltage and generate an operating voltage,
- an oscillator to provide a first pulse to the PSIP and a second pulse to the regulator, and
- a memory coupled to the regulator to receive the operating voltage.
A system, comprising:
- a power supply block coupled to receive a voltage potential;
- a regulator having an input coupled to an output of the power supply block;
- and
- an oscillator to provide a first signal to the regulator and a second signal to the power supply block.
A packaged device, comprising:
- (a) a power supply block coupled to receive a voltage potential;
- (b) a regulator having an input coupled to an output of the power supply block;
- and
- (c) an oscillator to provide a first signal to the regulator and a second signal to the power supply block.
A method, comprising:
- charging a first capacitor during a time that a first signal is active from a power-supply-in-package (PSIP);
- and
- charging a second capacitor from the first capacitor during a time that a second signal is active.
A method, comprising:
- selecting between a power-supply-in-package (PSIP) and an externally supplied power to provide an operating potential to a memory, wherein the memory and the PSIP are packaged together.
