Static Random Access Memory (SRAM) entries are constant and fixed, the information stored in this type of memory does not degrade over time. Dynamic Random Access Memory (DRAM) slowly leaks over time and must be refreshed from time to time.
This is incorrect. DRAM is a digital device, and so is SRAM. DRAM and SRAM serve the same functions- temporary storage space (or random access memory, hence 'RAM') in different ways. DRAM data is typically refreshed every so often, uses more power than SRAM and is much slower, but also much cheaper and easier to manufacture in huge sizes. SRAM, such as the cache on CPUs, is much smaller and faster, and stores data until it is cleared or the computer is turned off (and in some cases, even without power) but is extremely expensive.

DRAM has a lower price. Further details below:
DRAM and SRAM
Dynamic Random Access Memory contents need to be continuously refreshed. When its contents are being refreshed, memory can not be read from nor write to. Another point to note is that DRAM is cheap to manufacture (This could be the only advantage it has to SRAM).Where as in Static Random Access Memory, memory need not to be continuosly refreshed and therefore memory can be accessed at any time. SRAM is expensive to manufacture.
Five types of computer memory are: Dynamic Random Access Memory (DRAM) Synchronous DRAM (SDRAM) Static RAM (SRAM) Double Data Rate RAM (DDR) Rambus DRAM (RDRAM)
SRAM DRAM SDRAM XRAM is not a form of RAM.
SRAM is static RAM. It does not need to be refreshed like DRAM. Although it is faster than DRAM it is also very expensive. So it is not used computer prices would triple. Don't get that confused with SDRAM...that's a whole different story.

DDR and DDR2
---SRAM--- Static random access memory (SRAM) is a type of semiconductor memory where the word static indicates that it, unlike dynamic RAM (DRAM), does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence, but is still volatile in the conventional sense that data is eventually lost when the memory is not powered. The term SDRAM, which stands for synchronous DRAM, should not be confused with SRAM.
