Dimm memory ddr is a type of memory circuit which is integrated in a specialized manner and are used in the computers to perform different processes. Super models of dimm memory ddr are known as ddr2 and ddr3 respectively.
Dimm memory ddr contains a DDR SDRAM interface which makes transfer of data at a higher speed by controlling the timings of signals for clock and the electrically data running through the circuit. This is made possible by using different schemes such as loops and locked calibration which provide with the required time accuracy. Most of the interfaces in a dimm memory ddr use a dual transferring data process which lowers the clock time and usage. The main usage of keeping the clock time and frequency to a lower side is that the signal being transferred is more fast than normal. Dimm memory ddr is also known as double data rom as it provides more speed which is almost double the normal SDRAM but the clock frequency and speed is the same in both. This is only achieved by the double data pump used in dimm memory ddr. This means a 64 bits dimm memory ddr will transfer data at a rate of 64 × 2 than a simple SDRAM of the same clock frequency.
The other important point is that dimm memory ddr made for different operating systems use same number of free resources and provide with the same clock frequency speed in spite of its configuration. Dimm memory ddr also has the duality of running at a under clock or an over clock speed than the original speed it was initially made for. A normal dimm memory ddr has 184 pins more than a normal SDRAM containing 168 pins and the number of notches is 2 in a SDRAM but a dimm memory ddr has 1 notch. The operating voltage required by a dimm memory ddr is 2.5 V which were initially 3.3 V in a SDRAM thus reducing the power consumption by a dimm memory ddr. The operating system built for dim memory ddr has normal voltage range of .2.6 V. This increase in the system voltage also increases the maximum speed which can sometimes result in high power consumption and heat production which may lead to malfunctioning and even damage to the operating system. Now many new operating systems have built in multi channel configuration to reduce these risks.
Sometimes to increase the speed and capacity of a dimm memory ddr different chips are combined in a system with a common memory address also called as a memory rank address. A memory module can often have more than one rank and thus can perform at different clock speeds as required respectively. All of the ranks are interconnected to the main operating system by a single memory bus and the responses to different signals from the ranks depend upon the rank and the commands which follow the specific rank. By addition of different ranks the electrical load on drivers in added which is overcome by memory gating, newer models provide the users with multi channel architecture which is power efficient and user friendly thus providing the user with less power consumption and saves the time of the user.
