static
int
SRAM (Static Random-Access Memory) stores data using a bistable latching circuit, which eliminates the need for refreshing circuitry found in DRAM (Dynamic Random-Access Memory). The stored data in SRAM remains intact as long as power is supplied to the memory cells, making it faster and simpler to access compared to DRAM.
RAM
both are semiconductor memory. semiconductor means that both need continuous voltage or charge to sustain their data. SRAM used for cache , and store data in the flip flop, no need for refreshing , fast access but more expensive. DRAM used for main memory , and store data in capacitor, need for refreshing , slow access but less expensive.
It can be either depending on the type of RAM. Dynamic RAM (DRAM) requires constant refreshing and will lose its data if power is lost whereas Static RAM (SRAM) will retain its memory state. The majority of RAM in computers is DRAM and volatile. The most common form of non-volatile memory is flash, widely used for USB memory devices.
The amount of data/information the flash drive can store at one time.
Memories using capacitor cells, such as dynamic random-access memory (DRAM), need refreshing because the charge stored in the capacitors degrades over time due to leakage currents. This gradual loss of charge can lead to data corruption if not addressed. Refreshing involves reading the stored data and writing it back, which restores the charge and ensures data integrity. Without regular refreshing, the stored information would be lost, making it essential for maintaining accurate data in DRAM.

RAM is just memory your computer uses to run tasks while its on.
Semiconductor memories with DRam because each read operation requires discharging of capacitors in DRam.Besides,capacitors tend to degrade,so refreshing is needed from time to time
I believe this is known as dynamic memory. The most common dynamic memory is the RAM in your computer.
Paged memory is used to extend the real physical memory of the machine by copying blocks of data from the memory to a drive. That way you can run many programs simultaneously even if they consume more memory than you physically have in your computer. When a program requires to access the data that is "paged to disk" the operating system will read this data into memory.
