Management Notes
RAM (Random Access Memory) is the internal memory of the CPU for storing data, program and program result.It is read/write memory which stores data until the machine is working.As soon as the machine is switched off, data is erased so it is a volatile memory.RAM is of two types: Static RAM (SRAM) and Dynamic RAM (DRAM).The difference between SRAM and DRAM are as follows:
| S.No. | Static RAM (SRAM) | Dynamic RAM (DRAM) |
| 1. | Static RAM (SRAM) is a type of RAM which retains its contents as long as power is being supplied. | Dynamic RAM (DRAM) is a type of RAM which must be continually refreshed in order to maintain the data. |
| 2. | SRAM uses more space than DRAM for the same amount of storage capacity. | DRAM uses less space than SRAM for the same amount of storage capacity. |
| 3. | Manufacturing costs of SRAM are generally higher as compared to DRAM. | Manufacturing costs of DRAM are generally lower as compared to SRAM. |
| 4. | SRAM is faster and has long life as compared to DRAM. | DRAM is slower and has short life as compared to SRAM. |
| 5. | SRAM are larger in size and consume high power as compared to DRAM. | DRAM are smaller in size and consume low power as compared to SRAM. |
