because if you dont refresh the data stored in the floating node will leak out with time
DRAM
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.
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.
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.
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
Static RAM (SRAM) is generally faster than Dynamic RAM (DRAM). SRAM uses a more complex architecture that allows it to access data more quickly, making it suitable for cache memory in processors. In contrast, DRAM is slower because it requires periodic refreshing of its stored data. However, SRAM is also more expensive and takes up more space than DRAM, which is why DRAM is commonly used for main memory in computers.
SRAM (Static RAM) is an improved architecture of regular DRAM. Traditional DRAM is composed of a transistor and a capacitor which require periodic rewriting (refreshing) of information in order for data to remain valid. SRAM memory requires no refresh at all, it will maintain its information so long as it has sufficient power to keep it. This is due to the fact that internally, the SRAM component is made up of flip-flop circuitry, that does not depend on refreshing.
DRAM is volatile.
Short for static random access memory, and pronounced ess-ram. SRAM is a type of memory that is faster and more reliable than the more common DRAM (dynamic RAM). The term static is derived from the fact that it doesn't need to be refreshed like dynamic RAM. To store 1 bit of information about 6 transistors are used and it does not required refreshing. Because Six transistors are used to store 1 bit of information, it is more costlier than DRAM in terms of cost per bit, where only 1 transistor and 1 capacitor is used to store 1 bit of information.DRAM stands for dynamic random access memory, a type of memory used in most personal computers. In DRAM to store 1 bit of information 1 transistor and 1 capacitor is used. The information is stored in the capacitor in form of charge, so it required refreshing to retain the charge or data in the capacitor.SRAM is Static RAM and DRAM is Dynamic RAM. DRAM is slower than SRAM and needs to be refreshed where SRAM does not and is used for cache.(Static RAM) SRAM is similar to DRAM but does not constantly refresh. SRAM is faster and more expensive than DRAM and is generally used for speed-critical areas of the computer such as cache memory.(Dynamic Random Access Memory) DRAM is the most common type of memory and is "dynamic" because in order for the memory chip to retain data, it must be refreshed constantly (every few milliseconds). If the cell is not refreshed, the data is lost. DRAM temporarily stores data in a cell composed of a capacitor and a transistor. Each cell contains a specified number of bits. These cells are accessed by row addresses and column addresses.
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.
