ram[random access memory ] Flashcards
ram
a volatile memory that stores data and instructions the cpu needs quicky during execution.
characteristics
unlike rom ram allows data to be read & written.
Suitable for temporary storage.
It serves as the primary working memory,holding program code, application data and operating system Components in active use.
Speed and capacity
Faster than rom due to its internal location but with less storage capacity.
Types
Static ram (sram)
Dynamic ram (dram)
Static ram
Use flip flops to store data offering faster access without the need for refreshing.
Used in cache memory for high speed access.
Sram is faster and more reliable than dram but requires more space and power,making it more expensive.
Dram
Stores data with capacitors that require periodic refreshing.
Dram has higher storage densities and lower costs than sram but slower acces times.
It’s cost effective and space efficient,making it suitable for main memory.
