RAM
Construction
RAM (Random Access Memory) Memory for random access. It is constructed from many integrated circuits. RAM can be divided into two types:
Dynamic memory (DRAM) - this is a type of memory that needs frequent refresh, it causes a slower reading of information but at the same time simplifies the construction. This construction is used in the bones of operating memory.
Static memory (SRAM) - This type of memory is faster because it does not need refreshing, but it has less capacity. They are used as a cache, for example in processors or disks.
Memory modules
Currently, the most popular memory modules are DIMM DDR or simply DDR. Several versions of this memory have already been created. Individual modules of DDR memory can be recognized after the manufacturer's marking, or after the required power supply voltage
Name | Voltage | Max bandwidth |
---|---|---|
DDR | 2.5 | 3200 MB/s |
DDR 2 | 1.8 | 8533.33 MB/s |
DDR 3 | 1.5 | 17066.67 MB/s |
DDR 4 | 1.3 | 25600 MB/s |
