Memory power management systems and methods |
摘要 |
Memory power management systems and methods are provided. One embodiment of the present invention includes a memory power management system. The system comprises a first low dropout (LDO) regulator that provides an active operating voltage that is derived from a first supply voltage to power a memory array during an active mode. The system further comprises a second LDO regulator that provides a minimum memory retention voltage that is derived from a second supply voltage to power the memory array in a standby mode, wherein the second supply voltage also powers at least one peripheral circuit for reading from and/or writing to the memory array.
