Synchronous DRAM, however, has a CAS latency that is dependent upon the clock rate. Accordingly, the CAS latency of an SDRAM memory module is specified in clock ticks instead of absolute time.

DDR SDRAM, as the first generation of DDR memory, the prefetch buffer is 2bit, which is the double of SDR SDRAM. The transfer rate of DDR is between 266~400 MT/s. DDR266 and DDR400 are of this type.
In an 8n prefetch architecture (such as DDR3), ... DDR4 SDRAM's prefetch buffer size is 8n (eight datawords per memory access) Generations of SDRAM

Introduction We have no intention of getting into the disputes over which technology is better, Rambus or DDR SDRAM. Both have their place in the user environment, and they both have their positive, as well as negative, aspects.
However, your system will operate at the speed of the slowest memory module. One thing to keep in mind is that the memory does need to be the same type - for example, SDRAM cannot be mixed with DDR, and DDR cannot be mixed with DDR2 and DDR2 cannot work in a DDR3 system.
The Rambus inline memory module connected to an RDRAM motherboard using a 184-pin connector versus the 168-pin connector of the dual inline memory module used by SDRAM. In 1999, Direct Rambus DRAM was released, which provided a 16-bit bus, rather than SDRAM's initial 8-bit bus.
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.
Cache memory is a rather large subject, I'll not get too deep. Simply enough, there are many levels of caching for different devices. The slowest device is the Internet.
