An electro-optic module provides electro-optic signal drivers formed upon a semiconductor carrier having electrically conducting traces and passive circuit network filtering elements of electroceramic material with the electro-optic signal drivers being in electrical communication with the passive circuit ...
access time- (computer science) the interval between the time data is requested by the system and the time the data is provided by the drive; "access time is the sum of seek time and rotational latency and command processing overhead" ...
Note In block transfers, latency is used to denote the time it takes to transfer the first word of data. When buying DRAM, the latency rating that you see most often is the memory access time. Semiconductor RAM Memories (29) Synchronous DRAMs (SDRAMs) (ctd.) Latency and Bandwidth (ctd....
A computer memory access controller receives load and store requests from a plurality of parallel execution pipelines and forms queues of store and load addresses, comparator means compares load addresses with store addresses in a store address queue and selects a store before load if an address ma...
Tightly coupled multiprocessor system speeds memory-access times. Electronics, 57(1):164–169, January 1984. 101 [4] D. Kroft. Lockup-free instruction fetch/prefetch cache organization. In Proc. of the 8th Annual Symposium on Computer Architecture, May 1981. DOI: 10.1145/285930.285979. 100 [5...
If the sum is greater than the total physical memory, some of the instances do not start or have access to less memory than specified by the max server memory setting. For example, suppose a computer has 16 gigabytes (GB) of physical memory and three installed instances of SQL Server. ...
(NUMA), as shown inFig. 4. Today, the most common form of UMA architecture is theSymmetric Multiprocessor(SMP) machine, which consists of multiple identical processors with equal level of access and access time to the shared memory. Whereas the most common form of NUMA architecture is the ...
It is faster to access local memory than the memory associated with other NUMA nodes. This is the reason for the name, non-uniform memory access architecture. On NUMA hardware, some regions of memory are on physically different buses from other regions. Because NUMA uses local and foreign ...

in the hierarchy is the level-2 cache, followed by the main memory (RAM), and finally the hard disk drive.Figure 1shows the access time and sizes of the various parts of the memory hierarchy for a typical PC. At every step deeper into the memory hierarchy, the access time (and size...
