Purpose of RAM

• RAM is used to load and run programs or applications on a computer's operating system. More RAM means more applications and programs can be run simultaneously.
  
  

SRAM

• Static Random Access Memory, or SRAM, stores data on a computer in a static method, meaning the data stays the same with power being supplied to the memory chip. SRAM is the faster RAM when compared with DRAM.
  
  

DRAM

• Dynamic Random Access Memory, or DRAM, is a type of memory used in personal home computers. This type of memory must have an electrical current to refresh. DRAM is used more commonly because it's less expensive to manufacturer and install in chips.
  
  

EDO RAM

• Extended Data Output, or EDO, is a new type of DRAM chip that uses technology to add 10 to 15 percent more speed than normal. A computer that uses EDO technology must meet the chip requirements or the EDO will not be recognized.
  
  

FPM

• Fast Page Mode, or FPM, is a RAM speed enhancement that uses rows of bits selected in columns and rows of the memory. FPM is used in EDO RAM.
