Navigating Flash Storage Choices for Embedded OEM Design
DRAM (Dynamic Random Access Memory):
The reason for this temporary basis is because DRAM is volatile and loses all data when power is removed.
The advantages of DRAM are its fast performance and random access which allows access to individual bytes of data.
Disadvantages are the volatility and higher price than NAND based products.
The advantages of NOR flash is its fast read performance for processor instructions and its non-volatility.
Disadvantages are its slow write speeds and significantly more expensive architecture than NAND flash.
Data Storage Flash (aka NAND-Based Flash Storage):
The advantages of Data Storage Flash is its high performance read and write speeds, non-volatility and relative low cost. The disadvantage is that is cannot be addressed by byte, only by logical blocks.
