An SRAM cell has three different states it can be in: standby where the circuit is idle, reading when the data has been requested and writing when updating the contents. The SRAM to operate in read mode and write mode should have "readeability" and "write stability" respectively. The three different states work as follows: Standby, Reading, Writing, Bus behavior. A RAM memory with an access time of 70 ns will output valid data within 70 ns from the time that the address lines are valid. But the data will remain for a hold time as well (5-10 ns). Rise and fall times also influence valid timeslots with approximately ~5 ns. By reading the lower part of an address range bits in sequence (page cycle) one can read with significantly shorter access time (30 ns). FANUC A20B-2902-0351
