    Hi,

    I am looking for a small ram chip with a serial interface to hook up to an
    atmega8 micrcontroller. The microcontroller only has 1KB of internal sram,
    and I need to setup a first in last out buffer to log some data (4KB buffer
    would be enough). The update rate is about 4KB/second. I have an external
    serial flash memory chip (AT45DB series) but I don't know if I want to use
    it as a ram buffer as they are only rated to ~10K writes.. :)

    cheers,
    Jamie Morken
     
  2. Try FRAM from Ramtron wwwlramtron.com

    Endurance 10^12 (a million x a million) in I2c (FM24c16) or SPI
    (FM25c16)
