Memory is designed with this principle in mind and so, we should expect to see a decline in memory access time if we continually request addresses that are far apart from each other. It says that memory addresses which are near each other tend to be referenced close together in time. One principle of memory design is known as Spatial Locality. For instance, running an executable file from a disk causes Windows to copy the file from the disk to memory and then run the executable from there. Windows moves data onto and off of this strip as required. On 32 bit Windows platforms the size of each slot is 32 bits or 4 bytes ( 1 byte = 8 bits ). Each slot has a unique identifying value called its address. The strip is composed of millions (sometimes billions) of slots. You can think of computer memory as a long continuous strip. The Advanced Memory Test is part of the PerformanceTest application, and it is designed to test several factors which affect the speed of which data is accessed in PC memory.
