    High Speed AUTOSTORE NOVRAM
    DESCRIPTION
    The Xicor X20C16 is a 2K x 8 NOVRAM featuring a high-
    speed static RAM overlaid bit-for-bit with a nonvolatile
    electrically erasable PROM (E
    2
    PROM) and the
    AUTOSTORE feature which automatically saves the
    RAM contents to E
    2
    PROM at power-down. The X20C16
    is fabricated with advanced CMOS floating gate technol-
    ogy to achieve high speed with low power and wide
    power-supply margin. The X20C16 features a compat-
    ible JEDEC approved pinout for byte-wide memories,
    for industry standard RAMs, ROMs, EPROMs, and
    E
    2
    PROMs.
    The NOVRAM design allows data to be easily trans-
    ferred from RAM to E
    2
    PROM (store) and E
    2
    PROM to
    RAM (recall). The store operation is completed in 5ms or
    less and the recall operation is completed in 10
    μ
    s or
    less. An automatic array recall operation reloads the
    contents of the E
    2
    PROM into RAM upon power-up.
    Xicor NOVRAMS are designed for unlimited write
    operations to RAM, either from the host or recalls from
    E
    2
    PROM, and a minimum 1,000,000 store operations to
    the E
    2
    PROM. Data retention is specified to be greater
    than 100 years.
