ICC1, ICC3, ICC4 and ICC6 depend on cycle rate. ICC1 and ICC4 depend on output loading. Specified values are measured with the output open. Address can be changed once or less while RAS = VIL. In the case of ICC4 it can be changed once or less during a fast page mode cycle (tPC). 5. An initial pause of 200 µs is required after power-up followed by 8 RAS cycles of which at least one cycle has to be a refresh cycle, 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. 6. AC measurements assume tT = 5 ns. 7. VIH (MIN.) and VIL (MAX.) are reference levels for measuring timing of input signals. Transition times are also measured between VIH and VIL. 8. Measured with a load equivalent to 2 TTL loads and 100 pF. 9. Operation within the tRCD (MAX.) limit ensures 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. 10.Operation within the tRAD (MAX.) limit ensures 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. 11.Either tRCH or tRRH must be satisfied for a read cycle. 12.tOFF (MAX.) and tOEZ (MAX.) define the time at which the outputs achieve the open-circuit condition and are not referenced to output voltage levels. 13.Either tDZC or tDZO must be satisfied. 14.Either tCDD or tODD must be satisfied. 15.tWCS, tRWD, tCWD, tAWD and tCPWD 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 the I/O pin will remain open-circuit (high impedance) through the entire cycle; if tRWD > tRWD (MIN.), tCWD > tCWD (MIN.), tAWD > tAWD (MIN.) and tCPWD > tCPWD (MIN.), the cycle is a read-write cycle and I/O pins will contain data read from the selected cells. If neither of the above sets of conditions is satisfied, the condition of the I/O pins (at access time) is indeterminate. 16.These parameters are referenced to the CAS leading edge in early write cycles and to the WE leading edge in read-write cycles. 1. 2. 3. 4.

a test mode cycle using 8:1 compression can be used to improve test time. Note that in the 1M × 4 version the test time is reduced by 1/2 for a linear test pattern. In a test mode “write” the data from each I/O1 pin is written into eight bits simultaneously (all “1” or all “0”).The I/O2 - I/O4 inputs are not used for writing in test mode. In test mode “read” each I/O output is used for indicating the test mode result. If the internal eight bits are equal, the I/O would indicate a “1”. If they were not equal, the I/O would indicate a “0”. Note that in test mode „read“ I/O1-I/O3 are always driven to “ones”, i.e. all outputs will be “1” for a test mode “pass”. The WCBR cycle (WE, CAS-before-RAS) puts the device into test mode. To exit from test mode, a “CAS-before-RAS refresh”, “RAS-only refresh” or “Hidden refresh” can be used. Addresses A10R, A10C and A0C are don‘t care during test mode.
