High density, very low cost per byte stored, high power.
Moderate read and write speeds and bulky moving parts.
2. SRAM :
Super fast read and write speeds and low power consumption
Large memory cells take up more space, volatile
3. DRAM: High density, low cost, fast read and write speeds and low power
Volatile and require constant refreshing of data drains power
Nonvolatile, High density, fast read speed
More power consumtion, write operation is slow and limited life time
Non volatile, high density, fast read and write speeds, low power and unlimited lifetime
