Specified values are measured with the output open. 4) An initial pause of 200 s is required after power-up followed by 8 RAS cycles before proper device operation is achieved. In case of using internal refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required. 5) VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Transition times are also measured between VIH and VIL . 6) Measured with a load equivalent to 2 TTL loads and 100 pF. 7) tOFF (max.) defines the time at which the output achieves the open-circuit conditions and is not referenced to output voltage levels. 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 WE leading edge in read-write cycles. 10) tWCS , tRWD , tCWD and tAWD are not restrictive operating parameters. They are included in the data sheet as electrical characteristics only. If tWCS tWCS (min.), the cycle is an early write cycle and data out pin will remain open-circuit (high impedance) through the entire cycle; if tRWD tRWD (min.), tCWD tCWD (min.) and tAWD tAWD (min.), the cycle is a read-write cycle and DO will contain data read from the selected cell. If neither of the above sets of conditions is satisfied, the condition of DO (at access time) is indeterminate. 11) 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 by tCAC . 12) Operation within 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 by tAA . 13) AC measurements assume tT = 5ns.

In "Test Mode", data would be written into a number of sectors (4 sectors) in parallel and retrieved the same way. If upon reading, all bits are equal (all "H" or "L"), the data output pin indicates a same data as all bits. In this case, the data output pin indicates an expected data for good parts, the data output pin indicates a complementary data for bad parts. And also, if any of the bits differed, the data output pin would indicate a high impedance state for bad parts. The next figure shows the block diagram including its truth table when "Test Mode" is used. In test mode, 1M DRAM can be tested as if it were 256K DRAM by the following method. "Test Mode" function is performed on any of the timing cycles including fast page mode when "TF" pin is held on "super voltage (VCC + 4.5 V (VCC = 5 V 10 %), max. voltage = 10.5 V)" for the specified period (tTES , tTEHR and tTEHC ; see next figure). The address input of A9 is ignored in the "Test Mode". On the other hand, normal operation requires the "TF" pin be connected to VIL(TF) level, or left unconnected on the printed wiring board. The "Test Mode" function reduces test times (1/4; in case of using N test pattern). RAS V IH VIL tTEHC CAS V IH VIL tTES TF tTEHR V IH,TF VIL,TF Test Mode Cycle Semiconductor Group 54
