An initial pause of 200us is required after power-up followed by any 8 RAS-only 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. Transition times are measured between VIH(min) and VIL(max) and are assumed to be 5ns for all inputs. 3. Measured with a load equivalent to 1TTL loads and 100pF. Voh=2.0V and Vol=0.8V. 4. Operation within 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 tRCDtRCD(max). 6. This parameter defines the time at which the output achieves the open circuit condition and is not referenced to VOH or VOL. 7. tWCS, tRWD, tCWD and tAWD are non restrictive operating parameter. They are included in the data sheet as electrical characteristics only. If tWCStWCS(min) the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle. KMM372F400CK/CS KMM372F410CK/CS If tCWDtCWD(min), tRWDtRWD(min) and tAWDtAWD (min), then the cycle is a read-write cycle and the data output will contain data read from the selected address. If neither of the above conditions are satisfied, the condition of the data out is indeterminated. 8. Either tRCH or tRRH must be satisfied for a read cycle. 9. These parameters are referenced to the CAS leading edge in early write cycles and to the W leading edge in read-write cycles. 10. Operation within the tRAD(max) limit insures that tRAC(max) can be met. tRAD(max) is specified as reference point only. If tRAD is greater than the specified tRAD(max) limit, then access time is controlled by tAA. 11. tCEZ(max), tREZ(max), tWEZ(max) and tOEZ(max) define the time at which the output achieves the open circuit condition and are not referenced to output voltage level. 12. If RAS goes to high before CAS high going, the open circuit condition of the output is achieved by CAS high going. If CAS goes to high before RAS high going , the open circuit condition of the output is achieved by RAS high going. 13. tASCtCP min 14. The timing skew from the DRAM to the DIMM resulted from the addition of buffers.
