Abstract:
Disclosed herein are a SATA host bus adapter using a optical signal and a method for connecting SATA storage using the optical signal. The SATA host bus adapter includes: a first conversion unit for converting a PCI-Express signal, transmitted from a host computer, into a data signal, using a protocol defined in a bus; a optical signal conversion unit for converting the data signal into a optical signal and for transmitting the optical signal to a optical signal reception unit; and a second conversion unit for converting the optical signal, received by the optical signal reception unit, into the data signal, for converting the data signal into a SATA signal, using the protocol, and for transmitting the SATA signal to the SATA storage.
Abstract:
Disclosed are a double data rate synchronous dynamic random access memory module and a configuring method thereof. The DDR SDRAM module in accordance with an embodiment of the present invention includes: a plurality of memory chips; and a serial transceiver portion configured to serially receive first serial data including a control signal and data transferred from outside for the plurality of memory chips and to provide the control signal and the data included in the serially received first serial data to the plurality of memory chips.
Abstract:
Disclosed are an apparatus and method for interfacing between a central processing unit (CPU) and a main memory unit, whereby a shared cache memory unit and the main memory unit are connected to each other using one optical signal transmission line. The apparatus for interfacing between the CPU and the main memory unit includes: a master optical connection protocol engine, converting operation control signals received from a shared cache memory unit of the CPU into serial signals; a first electrical-to-optical (E/O) converter, converting the serial signals converted by the master optical connection protocol engine into optical signals; a second E/O converter, converting the optical signals converted by the first E/O converter into serial signals; a slave optical connection protocol engine, converting the serial signals converted by the second E/O converter into operation control signals; and a memory controller having access to the main memory unit.
