Different Types of RAM and ROM Memory

Static RAM (SRAM): SRAM needs a continuous supply of electric current to retain data. SRAM refers to a memory that stores data in a semiconductor. SRAM does not store data in a capacitor; therefor, it does not require refreshing, which makes it faster than DRAM. Due to this reason, SRAM is more expensive than DRAM.

Dynamic RAM (DRAM): It refers to the memory that stores every bit of information in a single capacitor. A capacitor is an electrical element that stores electrical charge. The electrical charge allows DRAM to store data. When there is no electrical charge, RAM loses the store data.

Synchronous DRAM (SDRAM): It refers to a type of DRAM that is synchronized with the clock speed of a processor to execute more data in less time. The clock speed of SDRAM is 133 MHz.
