Abstract
An associative memory that can reduce search errors is provided. An associative memory includes R distance/time conversion circuits DTto DT. The R distance/time conversion circuits DTto DTeach include a NAND circuitand N bit stagestok. The N bit stagestok delay a signal from the NAND circuitby longer delay time as the distance between reference data and search data is greater and oscillate the signal. Among R oscillation signals output from the distance/time conversion circuits DTto DT, the earliest changing oscillation signal is detected as an oscillation signal for the Winner row.
