摘要： An optics of a read/write system includes a stationary optical device for condensing a light beam and leading said light beam into an optical fiber. A distal end of the optical fiber is moveable and with a tapered configuration thereof for focusing the light emerging from the optical fiber into a beam spot on an optical recording medium. A detector detects through the optical fiber light reflected back from the recording medium.

摘要： A high performance optical circulator is formed by a polarization beam splitter and optical port assemblies. The polarization beam splitter is formed by two prisms with an interface between the prisms. The interface transmits linearly polarized light directed at the interface in directions responsive to a polarization orientation of linearly polarized light. The optical port assemblies are arranged with respect to the polarization beam splitter so that light from one port assembly is transmitted by the polarization beam splitter interface to another optical port assembly and light from this optical port assembly is transmitted by the beam splitter interface to still another optical port assembly.

摘要： A method and system for refreshing DRAM having a plurality of banks, each of the banks including a plurality of rows includes dividing all banks in DRAM into a plurality of groups of banks, each of the groups having n banks, wherein n is an integer greater than or equal to 1. A threshold of available retention time for each group of banks is determined. Each row of banks in each group of banks is refreshed. Refreshing one row of a bank in one group of banks includes determining whether a refresh operation for the row of the bank conflicts with an access operation for the bank where the row of the bank is located. If there is a conflict, then it is determined whether to perform the refresh operation or the access operation for the current row of the bank. If it is determined to perform the access operation, the access operation is continued. If it is determined to perform the recess operation, the current row of the bank is refreshed. DRAM access performance is improved.
