Non-ECC memory is computer memory that lacks error checking and correction functions. Non-ECC memory is the most common type of memory in consumer-grade computers; ECC memory is found in servers and scientific computing.Know More
Memory correction is not needed except in the most sensitive scientific and financial applications. Even slight amounts of data corruption are unacceptable in these usage cases, so memory with error correction capabilities is used. Most commercially available motherboards designed for home and small business use do not function with ECC memory.
The average incidence of memory error is once per gigabyte of memory per month of uninterrupted operation, as of 2014. Because very few home and small business machines have significant uninterrupted uptime, there is little risk of a memory error. In the rare case that a memory error does occur, a system restart corrects the issue. Because home systems do not require constant uptime, restarting the machine is an acceptable solution. Financial and scientific applications have greater need for uninterrupted uptime, and use ECC memory to prevent memory errors as a result.
Memory errors are caused by natural background radiation, which comes from both radioactive isotopes found on earth and cosmic rays originating in supernovas. The occurrence of memory errors is much higher for computers aboard spacecraft, particularly during solar flares and other events that increase the incidence of background radiation.Learn more about Computers & Hardware
Random access memory is used to store temporary but necessary information on a computer for quick access by open programs or applications. The data stored in RAM can be accessed randomly, meaning a computer does not need to search through large blocks of data to find what it needs. This targeted access makes it possible to run complex programs quickly and efficiently.Full Answer >
To determine how much memory a user has on their computer, they must access the hard drive information. This is fairly simple for users with Windows operating systems.Full Answer >
VRAM, which stands for video random access memory, is the dynamic random access memory used for storing image and video data for a computer. VRAM is an integrated circuit that operates as a buffer between the CPU and the computer's video card.Full Answer >
Associative memory in computer organization is when memory is accessed through content rather thanthrough a specific address. Associative memory is also known as associative storage, associative array or content-addressable memory, or CAM.Full Answer >
