There are two types of DRAM chips commonly used in embedded systems. PC DRAM chips are the DDR1, DDR2 or DDR3 parts that are used in almost all PCs and servers. Low-Power DRAM chips are the LPDDR1 and LPDDR2 parts used most often in cell phones and portable applications.
PC DRAM often is the lowest cost DRAM memory and often finds its way into consumer products, even though in many cases it’s not technically ideal for that purpose.
