Note 1: Address time is measured from the change of data olJ any input or Chip Enable line to the output of a TTL gate.

(See Timing Diagram.) See curves for guaranteed limit over temperature.

Note 2: Capacitances are measured periodically only,

Note 3:. The address time follows the following equation: T ACCESS

=

the specified limit + (N - 1) x 25 ns where N

=

Number of AND connections.

Note 4: Outputs open.

Note 5: All addresses and outputs are in negative true logic with the exception of LO. Ll. and L2 which are in positive logic.

MM1101lMM110111MM1101A/MM1101AlIMM1101A2, MM4250 256-bit fully decoded static random access memory

general description

The MMll0l family of fully decoded 256 word x l-bit random access memories are monolithic MOS integrated circuits using silicon gate low threshold technology to achieve bipolar compatibility. They are static, require no clocks, and hold information indefinitely, subject to the integrity of the power supply voltages.
