For storage, where data like photos and documents are kept, data integrity and storage longevity are far more important than speed. Today, capacity for a storage device can be in the terabyte range Flash memory is the primary type used for storage. Capacity to hold data and cost-efficient manufacturing are important, given the ever-growing demand to retain large volumes of data.
For memory, speed is critical because it holds the data currently being used and/or changed.
DRAM is the most common technology used for main memory because of its speed and ability to individually access the smallest unit of data, which are key requirements
Mobile DRAM (TSV)
TSV allows shorter IO connections therefore allowing higher bandwidth at lower power consumption.
MRAM can be defined as a non-volatile memory technology, which employs electron spinning for reversing the magnetization of a layer. This allows for the storing of the data in the memory, using electrical current. Unlike conventional RAMs, the MRAM has the ability to retain the data even when there is no power. It also has the ability to display high transfer speeds and consume less power.
