dram module m374f080(8)3dj3-c rev. 0.1 oct. 2000 notes 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. input voltage levels are v ih /v il . v ih (min) and v il (max) are ref- erence levels for measuring timing of input signals. transi- tion times are measured between v ih (min) and v il (max) and are assumed to be 5ns for all inputs. measured with a load equivalent to 1 ttl loads and 100pf. operation within the t rcd (max) limit insures that t rac (max) can be met. t rcd (max) is specified as a reference point only. if t rcd is greater than the specified t rcd (max) limit, then access time is controlled exclusively by t cac . assumes that t rcd 3 t rcd (max). this parameter defines the time at which the output achieves the open circuit condition and is not referenced to v oh or v ol . t wcs , t rwd , t cwd and t awd are non-restrictive operating parameter. they are inclueded in the data sheet as electrical characteristics only. if t wcs 3 t wcs (min), the cycle is an early write cycle and the data out pin will remain high impedance for the duration of the cycle. if t cwd 3 t cwd (min), t rwd 3 t rwd (min) and t awd 3 t awd (min), then the cycle is a read-write cycle and the data output will contain the data read from the selected address. if neither of the above conti- tions are satisfied, the condition of the data out is indeterni- mated. either t rch or t rrh must be satisfied for a read cycle. operation within the t rad (max) limit insures that t rac (max) can be met. t rad (max) is specified as a reference point only. if t rad is greater than the specified t rad (max) limit, then access time is controlled exclusively by t aa . if ras goes to high before cas high going, the open circuit condtion of the output is achieved by cas high going. if cas goes to high before ras high going, the open circuit cond- tion of the output is achieved by ras high going. t asc 3 6ns 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11.
