Abstract
A solid state drive (SSD) device includes a first nonvolatile memory package, a second nonvolatile memory package, and a controller. The first nonvolatile memory package includes a first buffer chip and a plurality of first nonvolatile memory chips. The second nonvolatile memory package includes a plurality of second nonvolatile memory chips. The controller controls the first nonvolatile memory package and the second nonvolatile memory package. The first buffer chip communicates a first address signal and a first data with the controller, and selectively communicates the first data with one of the plurality of first nonvolatile memory chips and the plurality of second nonvolatile memory chips based on the first address signal.
