Abstract
A storage device includes: an embedding vector manager for determining an estimated access frequency of each of a plurality of embedding vectors, based on a learning data set, and dividing the plurality of embedding vectors into a plurality of embedding vector groups, based on an order of the estimated access frequencies; and a plurality of memory cell arrays for each storing embedding vectors included in any one embedding vector group among the plurality of embedding vector groups.
Claims19
A storage device comprising:
- an embedding vector manager configured to determine an estimated access frequency of each of a plurality of embedding vectors, based on a learning data set, and to divide the plurality of embedding vectors into a plurality of embedding vector groups, based on an order of the estimated access frequencies;
- and
- a plurality of memory cell arrays each configured to store embedding vectors included in any one embedding vector group among the plurality of embedding vector groups.
A method of operating a storage device, the method comprising:
- determining an estimated access frequency of each of a plurality of embedding vectors, based on a learning data set;
- storing, in a first memory cell, upper embedding vectors with higher estimated access frequencies among the plurality of embedding vectors;
- and
- storing, in a second memory cell array, remaining embedding vectors among the plurality of embedding vectors, other than the upper embedding vectors.
