FUNCTION
operation mode M5M54R01J determined combination device control inputs Each mode summarized function table. write cycle executed whenever level overlaps with level address must set-up before write cycle must stable during entire cycle. data latched into cell trailing edge whichever occurs first, requiring set-up hold time relative these edge maintained. output enable input directly controls output stage. Setting high level, output stage high impedance state, data contention problem write cycle eliminated. read cycle excuted setting high level level while active state (S=L). When setting high level, chip non-selectable mode which both reading writing disable. this mode, output stage high-impedance state, allowing OR-tie with other chips memory expansion Signal-S controls power-down feature. When goes high, power dissapation reduced extremely. access time from equivalent address access time. works with organization 4194304-word bit,when B1/B4 floating. organization 1048 576-word 4bit also obtained reducing test time, when B1/B4 high.
