NOTE: RAMP, RAM0, RAM1 . . . , refer to the data that is present on the RAMs internal bus,
not necessarily data that resides in the RAM array. DPE is always delayed one
clock, and is registered on the rising edge of K at the beginning of the following clock
cycle (see AC CHARACTERISTICS).

NOTE: Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are
exceeded. Functional operation should be restricted to RECOMMENDED OPER-
ATING CONDITIONS. Exposure to higher than recommended voltages for
extended periods of time could affect device reliability.
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised
that normal precautions be taken to avoid
application of any voltage higher than maxi-
mum rated voltages to this high–impedance
circuit.
This CMOS memory circuit has been
designed to meet the dc and ac specifications
shown in the tables, after thermal equilibrium
has been established.
This device contains circuitry that will
ensure the output devices are in High–Z at
power up.
