Abstract
The invention discloses an analog content addressable memory (CAM) that employs analog storage cells with programmable analog transfer function capability. The analog CAM scans and/or compares its memory array contents to determine if an analog voltage applied at Vin matches a value stored in the memory array. If the value applied to Vin matches a value stored in the analog CAM, the analog data stored at a different and corresponding location in an analog storage cell is coupled to the Vout output. An analog content addressable memory, comprising a first array A of analog memory cells for storing and generating a VA voltage; and a comparator having a first input for receiving a Vin voltage, a second input for receiving the VA voltage from the first array A of analog memory cells. Analog-to-Digital and Digital-to-Analog Converters comprising an array of analog memory cells.
