Solid state disk controller apparatus

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 or from the first port to the second port;
• a host interface control block connected to the first port and the CPU bus and configured to interface with an external host according to a control of the central processing unit;
• a buffer controller/arbiter block connected to the CPU bus and configured to control the buffer memory according to a control of the central processing unit;
• a first FIFO configured to provide a data transfer path between the host interface control block and the buffer controller/arbiter block;
• a memory interface control block connected to the second port and the CPU bus and configured to interface with non-volatile memories according to a control of the central processing unit;
• and
• a plurality of second FIFOs configured to provide data transfer paths between the memory interface control block and the buffer controller/arbiter block.
