Since flash memory is a non volatile memory, all the data stored is not lost unless you do not erase or stored in the RAM memory. Flash memory comes in two forms namely NOR and NAND. NOR can easily access any type of memory location using the data busses and full addresses. However, NAND has faster writing and erase timings but doesn’t have random access. NAND flash memory is used for memory cards, but is not meant to be used as replacements for ROM chips. However, there are limitations to flash memories and the most significant being that flash can only be erased and rewritten only for finite number of times. But even though flash memory can be erased and rewritten for finite number of times, it is considered to be the most popular memory which can add difference to your computer and laptop and make it work efficiently. Next, we switch on to DDR memory. This type of memory is quite commonly used in desktop computers.
DDR memory also known as Double Data Rate has evolved from SDRAM and is twice faster than SDRAM. DDR memory can easily transfer data up to2133MB/s, and the best thing is that it consumes less of power than the traditional SD RAM memories. There are different types of variants of DDRs available in the RAM market. DDR1, DDR2 and DDR3 are the common types and you have to make sure that DDR memory you select is compatible with your computer system. Whether you have Dell, or HP, or Sony, or any other make, all that matters when you are buying memory upgrade is the compatibility. Dell memory upgrade is a right option to go ahead with, if you are thinking to increase the memory of our computer. To know precisely about the type of memory which is compatible with your Dell desktop or laptop, you need to opt for memory selector. The role of memory selector will be to find appropriate compatibility of DDR1, DDR2 or DDR3 memory upgrades with your Dell desktop or laptop.
