Abstract
A volatile memory device includes a memory array of volatile charge storage cells, a counter to track a time since the volatile memory device has received a read/write command and a control element to automatically change the volatile memory device to a lower power state based on the time tracked by the counter.
Claims12
A volatile memory device comprising:
- a memory array of volatile charge storage cells;
- a counter to track a time since the volatile memory device has received a read/write command;
- a control element to automatically change the volatile memory device to a lower power state based on the time tracked by the counter;
- and
- a buffer to store a page from the memory array;
- input/output circuitry, wherein the control element is to automatically rewrite the page from the buffer to the memory array and deactivate the buffer when automatically actuating the volatile memory device to the lower power state based on the time tracked by the counter.

A storage system comprising:
- a memory controller;
- a volatile memory device;
- a data bus connecting the memory controller and the memory device;
- and
- a command/address bus connecting the memory controller in the memory device, wherein the volatile memory device comprises:
- a memory array of volatile charge storage cells;
- a counter to track a time since the volatile memory device has received a read/write command;
- a control element to automatically change the volatile memory device to a lower power state based on a signal from the counter and
- a buffer to store a page from the memory array;
- input/output circuitry, wherein the control element is to automatically rewrite the page from the buffer to the memory array and deactivate the buffer when automatically actuating the volatile memory device to the lower power state based on the time tracked by the counter.
