A solid state disk controller apparatus comprises a first port; a second port having a plurality of channels; a central processing unit connected to a CPU bus; a buffer memory configured to store data to be transferred from the second port to the first port and from the first port to the second port; a buffer controller/arbiter block connected to the CPU bus and configured to control read and write operations of the buffer memory based on a control of the central processing unit; a first data transfer block connected between the first port and the buffer controller/arbiter block and configured to transfer data to be stored/read in/from the buffer memory bypassing the CPU bus; and a second data transfer block connected between the second port and the buffer controller/arbiter block and configured to transfer data to be stored/read in/from the buffer memory bypassing the CPU bus.

Solid state disk controller apparatus

A non-volatile memory device is operated by outputting data in response to an alternating sequence of first and second edges of a read control signal, respectively. A determination is made whether the read control signal and a write control signal are in synchronization at one of the first edges. Output of the data is stopped at the second edge that follows the one of the first edges of the read control signal if the read control signal and the write control signal are in synchronization at the one of the first edges.

Non-volatile memory devices for outputting data using double data rate (DDR) operations and methods of operating the same

We describe and claim an improved non-volatile memory storage device including an interface select switch and associated method. The device comprises a non-volatile memory, and an interface unit including a plurality of storage interfaces, the interface unit to select a storage interface from the plurality of storage interfaces responsive to a selection signal, where the non-volatile memory to exchange data with a host external to the device via the selected storage interface. In an embodiment, the selected storage interface is an ATA storage interface to convert the exchanged data in accordance with an ATA protocol when selected responsive to the selection signal. In another embodiment, the selected storage interface is a SATA storage interface to convert the exchanged data in accordance with a SATA protocol when selected responsive to the selection signal.

Non-volatile memory storage device including an interface select switch and associated method

A data storage device includes a memory block, a data classification unit, and a memory control unit. The memory block includes a high-speed nonvolatile memory and a low-speed nonvolatile memory, wherein a data access speed of the high-speed nonvolatile memory is greater than a data access speed of the low-speed nonvolatile memory. The data classification unit classifies the externally input data into data groups including busy data and free data, where the busy data has greater access frequency than the free data. The memory control unit configured to store the externally input data classified by the data classification unit as busy data in the high-speed nonvolatile memory, and to store the externally input data classified by the data classification unit as free data in the low-speed nonvolatile memory.
