Abstract

Big data analysis using low power circuit design including storing a plurality of data bits in a plurality of cells on a bitline of a dynamic random access memory (DRAM), wherein each data bit corresponds to a test result, and wherein each of the plurality of cells on the bitline is associated with a different wordline; precharging the bitline to a midpoint voltage between a low voltage corresponding to a low data bit and a high voltage corresponding to a high data bit; activating, at the same time, each wordline associated with each of the plurality of cells on the bitline, wherein activating each wordline causes a voltage to be applied to the bitline from each of the plurality of cells; and measuring a resulting voltage on the bitline to obtain a value corresponding to a percentage of the test results that indicate a passing test result.
