Memory with dynamic voltage scaling

Abstract:

Methods and apparatuses for to memories using dynamic voltage scaling are presented. The apparatus includes memory configured to communicate with a host. The memory includes a peripheral portion and a memory array. The memory is further configured to receive, from at least one power management circuit, a first supply voltage and a second supply voltage. The memory further includes a switch circuit. The switch circuit is configured to selectively provide the first supply voltage and the second supply voltage to the peripheral portion. The first supply voltage is static and has a first voltage range. The second supply voltage has a low second voltage range and a high second voltage range.
