Abstract
A Solid State Disk (SSD) includes a plurality of nonvolatile memory devices storing data, and an embedded solid state disk controlling the plurality of nonvolatile memory devices. The SSD uses an embedded SSD (eSSD) as a controller. Thus, the SSD can be embodied in a small area. Also, since the SSD does not need an additional process for manufacturing a controller, manufacturing cost per unit may be reduced.
Claims20
A solid state disk comprising:
- at least one first nonvolatile memory device configured to store data;
- and
- an embedded solid state disk configured as a single package within the solid state disk and configured to control the at least one first nonvolatile memory device via a plurality of nonvolatile memory channels,
- wherein the embedded solid state disk comprises at least one second nonvolatile memory device internal to the single package and at least one volatile memory device internal to the single package,
- wherein connectors of the plurality of nonvolatile memory channels for electrically connecting between the at least one first nonvolatile memory device and the embedded solid state disk are disposed at an outer side of the embedded solid state disk,
- wherein the at least one first nonvolatile memory device is external to, and separate from, the single package of the embedded solid state disk, and
- wherein the at least one volatile memory device internal to the single package is configured to store data temporarily while awaiting storing in the at least one first nonvolatile memory device and the at least one second nonvolatile memory device internal to the single package.
4 more elements
An embedded solid state disk comprising:
- a single package;
- an internal central processing unit in the single package;
- an internal volatile memory in the single package;
- an internal nonvolatile memory in the single package and configured to store data under control of the internal central processing unit;
- and
- a plurality of external memory interfaces in the single package, a respective one of which is configured to interface with a respective one of a plurality of external nonvolatile memories located outside the single package, under control of the internal central processing unit,
- wherein the internal volatile memory in the single package is configured to store data temporarily while awaiting storing in the internal nonvolatile memory in the singe package and the plurality of external nonvolatile memories.
4 more elements
A solid state disk comprising:
- a single package embedded solid state disk that includes therein an internal solid state disk controller internal to the single package, an internal nonvolatile memory internal to the single package, and an internal volatile memory internal to the single package;
- and
- a plurality of external nonvolatile memory device packages that are external to the single package embedded solid state disk and are connected to the single package embedded solid state disk, the internal solid state disk controller internal to the single package being configured to control the plurality of external nonvolatile memory device packages that are external to the single package,
- wherein the internal volatile memory internal to the single package is configured to store data temporarily while awaiting storing in the internal nonvolatile memory internal to the single package and the plurality of external nonvolatile memory device packages.
