Abstract :
A newly developed parallel image processing RAM (PIP-RAM) integrates 128 processor elements and a 16-Mb DRAM on a single chip. The paper presents three novel circuit design techniques: a data path control and synchronization scheme between processors and memory; a refresh scheme which enables refresh operations in parallel with arithmetic-logical operations; and a special block redundancy scheme
