This is incorrect. DRAM is a digital device, and so is SRAM.
DRAM and SRAM serve the same functions- temporary storage space (or random access memory, hence 'RAM') in different ways.
DRAM data is typically refreshed every so often, uses more power than SRAM and is much slower, but also much cheaper and easier to manufacture in huge sizes.
SRAM, such as the cache on CPUs, is much smaller and faster, and stores data until it is cleared or the computer is turned off (and in some cases, even without power) but is extremely expensive.
Static RAM and dynamic RAM are two available types of computer RAM, or Random Access Memory. One advantage of static RAM is speed, while a disadvantage is cost. An advantage of dynamic RAM is storage space, while a disadvantage would be speed.
The primary electrical component used for memory logic is the transistor. Transistors act as switches or amplifiers in digital circuits, enabling the storage and retrieval of binary data. In memory chips, such as SRAM (Static Random-Access Memory) and DRAM (Dynamic Random-Access Memory), arrays of transistors are utilized to hold and manipulate data. Additionally, capacitors are used in DRAM to store charges representing bits of information.
SRAM-based FPGAs use static random-access memory cells to store configuration data, allowing for reprogrammability and flexibility in design changes. In contrast, antifuse-based FPGAs utilize a one-time programmable technology where connections are made by creating permanent links during the programming process. This means that while SRAM FPGAs can be reconfigured multiple times, antifuse FPGAs are set once and cannot be altered afterward. Consequently, SRAM-based FPGAs are often favored for applications requiring frequent updates, while antifuse FPGAs may be preferred for their security and reliability in fixed-function applications.
SRAM based FPGAs cant be used for space application But we can go for Radiation tollerant Anti fuse FPGA.
Memory refers to the physical devices used to store programs (sequences of instructions) or data (e.g. program state information) on a temporary or permanent basis for use in a computer or other digital electronic device. Computer Memory is two types as Primary Memory and Secondary Memory at the base of uses. The term primary memory is used for the information in physical systems which function at high-speed (i.e. RAM), as a distinction from secondary memory, which are physical devices for program and data storage which are slow to access but offer higher memory capacity. When data of Primary Memory stored on secondary memory is called "virtual memory".Primary MemoryThe term "memory" is often (but not always) associated with addressable semiconductor memory, i.e. integrated circuits consisting of silicon-based transistors and used as primary memory. Primary storage (or main memory or internal memory), often referred to simply as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required. Any data actively operated on is also stored there in uniform manner. RAM used for primary storage is also volatile, i.e. they lose the information when not powered). Cash Memory is also a super fast then RAM and it working for only processor.There are two main types of semiconductor memory: volatile and non-volatile.Examples of non-volatile memory are flash memory (sometimes used as secondary, sometimes primary computer memory) and ROM/PROM/EPROM/EEPROM memory (used for firmware such as boot programs). Examples of volatile memory are primary memory (typically dynamic RAM, DRAM), and fast CPU cache memory (typically static RAM, SRAM, which is fast but energy-consuming and offer lower memory capacity per area unit than DRAM).Secondary MemoryThe term "storage" is often (but not always) used in separate computers of traditional secondary memory such as tape, magnetic disks and optical discs (CD-ROM and DVD-ROM). Secondary storage (also known as external memory or auxiliary storage), differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers the desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down-it is non-volatile. Hard disk, CD and DVD drives are usually used as secondary storage. Some other examples of secondary storage technologies are: flash memory (e.g. USB flash drives or keys), floppy disks, magnetic tape, paper tape, punched cards, standalone RAM disks, and Iomega Zip drives.

DRAM has a lower price. Further details below:
SRAM is less dense than DRAM because SRAM cells are made up of multiple transistors, typically 6 transistors per cell, which require more space compared to the single transistor used in DRAM cells. This extra space needed for each cell in SRAM makes it less dense in terms of storing data compared to DRAM.
DRAM and SRAM
Dynamic Random Access Memory contents need to be continuously refreshed. When its contents are being refreshed, memory can not be read from nor write to. Another point to note is that DRAM is cheap to manufacture (This could be the only advantage it has to SRAM).Where as in Static Random Access Memory, memory need not to be continuosly refreshed and therefore memory can be accessed at any time. SRAM is expensive to manufacture.

DDR and DDR2
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.
•Dynamic cell (DRAM) -Simpler to build, smaller -More dense -Less expensive -Needs refresh -Larger memory units •Static (SRAM) -Faster -Cache
---SRAM--- Static random access memory (SRAM) is a type of semiconductor memory where the word static indicates that it, unlike dynamic RAM (DRAM), does not need to be periodically refreshed, as SRAM uses bistable latching circuitry to store each bit. SRAM exhibits data remanence, but is still volatile in the conventional sense that data is eventually lost when the memory is not powered. The term SDRAM, which stands for synchronous DRAM, should not be confused with SRAM.
