Samsung patents memory that moves data to save power

Samsung describes a memory chip design that uses a controller to move data between different sections, or banks, of the memory. When one section is turned off to save energy, the system redirects the data request to a different section that is still active.

Why it mattersThis improves battery life in devices like phones and laptops by ensuring data can still be accessed even when parts of the memory are powered down.

In the filing’s own words

The present disclosure relates to electronic devices, memory devices, and memory device operating methods. An example memory device includes a first bank, a second bank, a cache controller, and a way selector. The first bank includes a first way group configured to receive power and to store a first cache line corresponding to a first address. The second bank includes a second way group configured to receive power and to store a second cache line corresponding to a second address. The cache controller is configured to output a second target indicating the second bank based on a power control signal indicating to stop supplying the power to the first bank and the first address. The way selector is configured to transmit the first address to the second bank based on the first address, the power control signal, and the second target.

What exactly they claim (claim 1)

1. A memory device comprising: a first bank comprising a first way group, the first way group configured to receive power, and store a first cache line corresponding to a first address; a second bank comprising a second way group, the second way group configured to receive power, and store a second cache line corresponding to a second address; a cache controller configured to generate, based on a power control signal and the first address, a second target indicating the second bank, the power control signal indicating to stop supplying the power to the first bank, and transmit the second target to a way selector; and the way selector configured to transmit the first address to the second bank based on the first address, the power control signal, and the second target.
