    World's first 64Mbit 3V Asynchronous SRAM

    prashanth.jnanendra

      Cypress packs 64Mbit memory in SRAM chips that are sized 8.0 mm x 9.5 mm. To get a comparable estimate of the size, the 1 dollar coin has a diameter of 26.5mm. That is, the dollar coin covers an area equivalent to 7 such chips. Talk about value for money!

      These chips are designed to operate at a cycle time of 12ns. What is the timescale equivalent to? Well, the human heart pumps blood 72 times every minute. In that one minute, the Cypress chip can support 5 billion read / write operations! One can only marvel at such technological prowess.

      The chips have been built in 90nm CMOS technology. That is, a single transistor could be as tiny as 90 nm in length. What is the dimensional equivalent?  The human hair is roughly that thick, irrespective of the shampoo / conditioner that we use!. Imagine a switch (or a transistor!) that could be only as wide as a single hair strand!

      These chips are guaranteed for high performance and cater to niche markets including storage servers, switches and routers, testing equipment, high-end security systems and military systems

      And in what packages do these "dynamites" come in? They are available in RoHS-compliant 48-BGA packages with the smallest footprint.

      The I/O configurations supported are both 16-bit and 8-bit, with a power supply of 3V.
