Abstract
: An analog RAM has been designed to act as a cache memory for a CNN Universal Machine. Hence, all the non-standard chips are available for the CNN Chipset architecture. Time-multiplexed analog routines in the CNN processor require fast and efficient short-time signal storage in an analog buffer. This can be achieved by an extended sample and hold scheme able to address every sample to specific memory locations. Several arrays of capacitors are multiplexed sharing controlling circuitry and I/O buses. The design has the following key parameters: 637 analog memory cells/mm 2 with 0.4% accuracy, 100ns access time and 170ms storage time (within 1% error). 1. Introduction An analog random access memory (ARAM) chip has been designed and integrated in a 0.5m n-well, singlepoly, triple-metal CMOS technology. This circuit is the only missing important part of the chipset of the CNN universal machine [1] [2]. It works as a memory cache for the analog visual microprocessor. In order to take a...
