What are the two most common types of memory modules?
Two types of DIMMs (dual in-line memory modules): a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom).
What does RIMM mean?
Rambus inline memory module
While RIMM is commonly believed to stand for “Rambus inline memory module,” Kingston Technology has trademarked “RIMM” and uses only that term. A RIMM module consists of RDRAM chips that are attached using a thin layer of solder, a metal alloy that, when melted, fuses metals to each other.
How many bits is RIMM?
The standard 16/18-bit RIMM has 184 pins, one notch on either side, and two notches centrally located in the contact area. The 16-bit versions are used for non-ECC applications, whereas the 18-bit versions incorporate the additional bits necessary for ECC.
Which is fastest main memory or secondary memory?
RAM provides a much faster-accessing speed to data than secondary memory. By loading software programs and required files into primary memory(RAM), computers can process data much more quickly. Secondary Memory is slower in data accessing. Typically primary memory is six times faster than secondary memory.
What are the two configurations of SIMM chips?
There are two distinct types: a 30-pin module for older x86 computers and a 72-pin module common in 486 and Pentium systems.
What is SDRAM in laptop?
SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.
What is RAM bus speed?
System RAM speed is controlled by bus width and bus speed. Bus width refers to the number of bits that can be sent to the CPU simultaneously, and bus speed refers to the number of times a group of bits can be sent each second.
What are 3 types of ROM?
Let us now discuss the various types of ROMs and their characteristics.
- MROM (Masked ROM)
- PROM (Programmable Read Only Memory)
- EPROM (Erasable and Programmable Read Only Memory)
- EEPROM (Electrically Erasable and Programmable Read Only Memory)
- Advantages of ROM.
Which memory is fastest?
Fastest memory is cache memory.
