4/6/2024 0 Comments Nand nor flashRAM has evolved over the years, but a common type of RAM in use today is DDR DRAM, which stands for “Double Data Rate Dynamic Random Access Memory.” You will often hear someone referring to RAM as DDR or DRAM they are merely identifying the specific type of RAM. Although RAM is fast, it loses everything whenever it loses power. Random Access Memory (RAM) is the working memory for processors to temporarily store data while executing code. Examples of non-volatile memory include flash memory. Non-volatile memory does not lose data when power is gone. MCU processors are a computing engine only cannot work without software, which the system holds in non-volatile memory. MCUs often use external flash memory to store boot code. Skip this section if you are familiar with MCUs and memory. Both NOR and NAND flash have a place in embedded systems, however. NAND and NOR flash memories are used both externally and integrated with MCUs onto System-on-Chips (SoCs) and memory usage trends are evolving around other changes in technology. Not everyone is familiar with the jargon that experienced engineers and technicians use when they talk about Microcontrollers (MCUs) and memory.
