• SDRAM (synchronous dynamic random-access memory) is a type of dynamic random-access memory that is synchronised with the system bus. RDRAM is a form of memory that has a maximum speed of 100 MHz and can transport data at up to 800 MHz.
• RDRAM is a form of memory that has a maximum speed of 100 MHz and can transport data at up to 800 MHz. RDRAM was supposed to become a VRAM standard, but it got caught up in a standards battle with DDR SDRAM, losing out on price and performance.
• SDRAM stands for synchronous dynamic random access memory and is synchronised with the system bus. It operates at a higher clock rate than traditional memory, at 133 MHz. It is also the forerunner of the DDR SDRAM modules that we use today in our PCs. Because SDRAM has a synchronous interface, it must wait for a clock signal before reacting to control inputs.
