WebLPDDR. Low-Power Double Data Rate ( LPDDR ), also known as LPDDR SDRAM, is a type of synchronous dynamic random-access memory that consumes less power and is targeted for mobile computers and devices such as mobile phones. Older variants are also known as Mobile DDR, and abbreviated as mDDR. Modern LPDDR SDRAM is distinct from DDR … WebDDR (Double Data Rate) SDRAM was introduced as a replacement for SDRAM memory running at bus speeds over 75MHz.
