Adding ram memory

I would like to add ram memory to a stamp project. I want an on-board
solution, not Solutions 3 rampack. Has anyone designed a RAM
interface?

Thanks,
George

    Hi,

    If 56 bytes of ram is enough you could
    consider the Timekeeper module at http://www.high-techgarage.com
    This module is placed under your stamp BS2 dip 24.
    Provides also RTC and extra Eeprom.

    Greetings peter

    I'm in the process of designing a RAM interface for 8kb and 32kb
    SRAM. When I started with the concept, I did not know about the
    Solutions^3 device. My original device would be in direct
    competition with theirs, and so I decided to transform my design
    into a kit. The kit version will be much more versatile, possibly
    even allowing several SRAM modules on one device! I currently only
    have 8KB and 32KB modules to test with. It will also be separate
    chips not on a PCB, so you can integrate it into any circuit! Price
    and features are not written in stone yet, though I plan to have
    serin/serout AND shiftin/shiftout communications using only 2 pins.
    I won't go into more detail now, but I believe my interface design
    may be what you need. I should be done with the design by sunday.
    The code and circuit design is mostly finished, but I have to test
    it with the actual chip and add any extra features (like automatic
    baud rate discovery and scalability). No more details now, maybe
    later. If you're interested, send me an e-mail and I'll get back to
    you about what's going on!

    THanks for the suggestion, Peter. I failed to mention that I need at
    least 8K, preferably 32K of RAM. I have a DS1302 in the system
    already.

    How about one of those serial RAMS? Would they work for you? No design
    needed one output line and write to them like a serial port. SOunds to
    easy???
