An initial pause of 200us is required after power-up followed by any 8 /RAS-only refresh or /CAS-before-/RAS refresh cycles before proper device operation is achieved. 2. Input voltage levels are VIH / VIL. VIH(min) and VIL(max) are reference levels for measuring timing of input signals. Also, transition times are measured between . VIH and VIL are assumed to be 5ns for all inputs. 3. Measured with a load circuit equivalent to 2TTL loads and 100pF. 4 HANBit Electronics Co.,Ltd. HANBit HMD2564Z1 4. Operation with the tRCD (max) limit insures that tRAC (max) can be met, tRCD (max) is specified as a reference point only, if tRCD is greater than the specified tRCD(max) limit, then access time is controlled exclusively by tCAC . 5. Assumes that tRCD <= tRCD (max). 6. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to VOH / VOL . 7. TWCS, TRWD, TCWD, TCPWD are non restrictive operating parameter. They are included in the data sheet as electrical characteristics only. If twcs >= twcs (min), the cycle is an early write cycle and the data out pin will remain open circuit (high impedance) throughout the entire cycle. If tCWD >= tCWD (min), tRWD >= tRWD (min), TCPWD>= TCPWD(min), then the cycle is a read-modify-write cycle and the data output will contain the data read from the selected address. If neither of the above conditions is satisfied, the condition of the data out is indeterminate. 8. Either tRCH or tRRH must be satisfied for a read cycles. 9. These parameters are referenced to /CAS falling edge in early write cycles and to /WE falling edge in /OE controlled write cycle and read-modify-write cycles. 10. Operation with the tRAD (max) limit insures that tRAC (max) can be met, tRAD (max) is specified as a reference point only, if tRAD is greater than the specified tRAD (max) limit, then access time is controlled exclusively by tAA. 11. tASC, tCAH are are referenced to the earlier /CAS falling edge. 12. tCP is specified from the later /CAS rising edge in the previous cycle to the earlier /CAS falling edge in the next cycle. 13. tCWD is referenced to the later /CAS falling edge at word read-modify-write cycle. 14. tCWL is specified from /WE falling edge to the earlier /CAS rising edge . 15. tCSR is referenced to the earlier /CAS falling edge before /RAS transition low. 16. tCHR is referenced to the later /CAS rising edge after /RAS transition low.
