Patent ID: 11163453

Abstract:
A memory device comprises a smart buffer, and a memory area divided into a first memory area and a second memory area, wherein the smart buffer comprises a priority setting unit configured to receive a sensing data and a corresponding weight from a controller, determine a priority of the sensing data based on the weight, and classify the sensing data as one of first priority sensing data and second priority sensing data, and a channel controller configured to allocate at least one channel selected from among a plurality of channels to a first channel group, allocate at least another channel selected from among the plurality of channels to a second channel group, assign the first channel group to process the first priority sensing data in relation to the first memory area, and assign the second channel group to process the second priority sensing data in relation to the second memory area, wherein a number of data input/output (I/O) pins connected to the first channel group is greater than a number of data I/O pins connected to the second channel group, wherein the memory area includes at least one memory chip, wherein the at least one memory chip includes a first chip having a first metal pad and a cell region and a second chip having a second metal pad and a peripheral circuit region, and the first chip and the second chip are vertically connected to each other by the first metal pad and the second metal pad.
