EMBEDED SOLID STATE DISK AND SOLID STATE DISK

摘要

PURPOSE: An embedded solid-state disk (eSSD) and a solid-state disk (SSD) are provided to reduce production cost by eliminating the need of a separate process to produce a controller. CONSTITUTION: Non-volatile memory devices (342-34n) store data, and an eSSD (400) controls the non-volatile memory devices. The eSSD includes a first layer containing control logic and a second layer which is laminated on the upper part of the first layer and contains a non-volatile memory. The second layer includes a volatile memory temporarily storing data. The eSSD includes non-volatile memory interfaces performing interfacing operations with the non-volatile memory devices.
