Types of ram Memory
Find out why CAS latency isn't an accurate measure of memory performance and how speed might be a more important factor when looking to upgrade your RAM.
Double data rate (DDR) is the advanced version of synchronous dynamic random access memory (SDRAM). SDRAM waits for clock signals before responding to control inputs.
A DIMM (dual in-line memory module) is a double SIMM (single in-line memory module). Like a SIMM, a DIMM is a module that contains one or several random access memory chips on a small circuit board with pins that connect it to the computer motherboard.
Dynamic random-access memory (DRAM) is a type of random access semiconductor memory that stores each bit of data in a separate tiny capacitor within an integrated circuit. The capacitor can either be charged or discharged; these two states are taken to represent the two values of a bit, conventionally called 0 and 1.
EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage.

Random Access Memory (RAM) is the hardware in a computing device where the operating system , application programs and data in current use are kept so they can be quickly reached by the device's processor.
Memory is designed to be backward-compatible, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory. However, your system will operate at the speed of the slowest memory module.
Programmable read-only memory (PROM) is read-only memory ( ROM) that can be modified once by a user. PROM is a way of allowing a user to tailor a microcode program using a special machine called a PROM programmer.
Rambus Dynamic Random Access Memory (RDRAM) is a memory subsystem designed to transfer data at faster rates. RDAM is made up of a random access memory (RAM), a RAM controller and a bus path that connect RAM to microprocessors and other PC devices.
ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on.
What is SDRAM Memory SDRAM is the name for any dynamic random-access memory DRAM where the operation the external interface is synchronised by an external clock signal - hence the name synchronous DRAM.
Static random access memory (SRAM) is a lot faster and does not require refreshing like dynamic RAM. While SRAM can operate at higher speeds than DRAM, it is more expensive to manufacture because of its complex internal structure, so most of the RAM on the motherboard is DRAM.
Synchronous dynamic random-access memory (SDRAM) is any dynamic random-access memory (DRAM) where the operation of its external pin interface is coordinated by an externally supplied clock signal.
