A Solid State Drive (SSD) controller is disclosed. When a data read command is transmitted by a host, the SSD controller may select a representative pointer from at least one first pointer by checking a point in time when data writing is completed in a buffer by at least one memory, read the data from the buffer by referring to a second pointer, and transmit the read data to the host, based on the representative pointer.

A semiconductor chip and a semiconductor system comprising the chip. The semiconductor system comprises: a serial advanced technology attachment (SATA) host; a plurality of SATA devices which receive data from the SATA host and stores the received data, or transmit the stored data to the SATA host; and a semiconductor chip which controls a data-transceiving operation between the SATA host and the SATA devices. The semiconductor chip and the semiconductor system have merits in that the semiconductor chip may be connected to a plurality of devices without being limited by the number of host channels of the semiconductor chip, while preventing an increase in the size of a host.

A variable length code decoder for MPEG (Motion Picture Expert Group) includes a barrel shifter for outputting the bit stream being decoded, a register for storing the output data of the barrel shifter, a finite state machine for parsing the output data of the barrel shifter and determining whether the data is an ordinary data or a more than 16-bit data, and outputs resultant control signals, a multiplexer for selectively outputting the output data of the barrel shifter or the register based on the control signal, and a decoding units for decoding a variable length code, a header code of a MPEG2 syntax from the output of the multiplexer in accordance with the control signal of the finite state machine. The variable length code decoder obtains a data throughput rate equivalent to the using of 32-bit data path.
