Samsung patents memory chip that controls data sections separately

Patent drawing
Patent drawing from the official filing.

Samsung has filed a patent for a memory device that divides storage into separate sections called planes. The design uses distinct control signals to turn individual sections on or off, allowing the chip to manage data access more precisely.

Why it mattersThis technical improvement could help computer manufacturers build memory chips that handle data tasks more efficiently.

In the filing’s own words

A memory device includes a plurality of planes and a control circuit. The plurality of planes may be included in a chip, and each of which may include a cell array and a page buffer. The control circuit, in a first mode, may enable or disable at least one first plane among the plurality of planes based on a signal received through a first chip enable pad and output a signal that indicates a state of the at least one first plane through a first ready/busy pad. The control circuit may also enable or disable at least one second plane among the plurality of planes based on a signal received through a second chip enable pad and output a signal that indicates a state of the at least one second plane through a second ready/busy pad.

What exactly they claim (claim 1)

1. A memory device, comprising: a plurality of planes included in a chip, and each of which includes a cell array and a page buffer; and a control circuit, wherein the control circuit, in a first mode, is configured to: enable or disable at least one first plane among the plurality of planes based on a signal received through a first chip enable pad and output a signal that indicates a state of the at least one first plane through a first ready/busy pad; and enable or disable at least one second plane among the plurality of planes based on a signal received through a second chip enable pad and output a signal that indicates a state of the at least one second plane through a second ready/busy pad.
