Registered RAM modules are commonly used in servers and equipment. They contain integrated circuits that regenerate address and control signals using an onboard PLL. Data signals pass directly from the memory bus to the RAM ICs. RAM is used as working memory by the operating system, programs, and software. Within the system hierarchy, RAM sits below processor registers and caches as relatively fast, medium-capacity memory. Current RAM technologies use synchronous signals synchronized to the memory bus clock, unlike older asynchronous designs. RAM modules are printed circuit boards containing silicon memory chips attached via copper or pins.

1. RAM Memory ( Random-Access Memory )

2. Registered RAM Module is a type often used in servers and equipment. They have integrated circuits that are responsible to repeat the address and control signals. The clock signals are reconstructed using the PLL, which is located on the module itself. The data signals pass directly from the memory bus to the RAM IC.

3. RAM Memory Usage It is used as working memory for the operating system, programs and most of the software. This is where you load all the instructions that run the processor and other units of computation.

4. Relationship with the rest of the system Within the hierarchy of the RAM memory is at a level after the processor registers and caches. It is a relatively fast memory and an average capacity: about 2010, it was easy to find memories at speeds over 1 GHz, and capacities up to 8 GB per module, coming to see memories passing the 3 Ghz barrier for this same date.

5. Memory Technologies The current memory technology uses a sync signal for the read-write so that is always synchronized with a clock of the memory bus, unlike the older FPM and EDO memory that were asynchronous. More than a decade ago the industry opted for synchronous technologies, allowing to build integrated operating at a frequency above 66 MHz

6. What is RAM memory formed? RAM modules are printed circuit boards with silicon semiconductor soldiers, in the case of SIMM type on, copper is used for the area where the plug (your pin). As printed circuit boards (such as motherboards or graphics cards, etc), the RAM modules can be made of fiberglass and other composites.
