The device is fabricated in SIEMENS/IBM most advanced first generation 64Mbit CMOS silicon gate process technology. The circuit and process design allow this device to achieve high performance and low power dissipation. This DRAM operates with a single 3.3 +/-0.3V power supply and interfaces with either LVTTL or LVCMOS levels. Multiplexed address inputs permit the HYB 3164(5)400J/T to be packaged in a 500mil wide SOJ-34 or TSOP-34 plastic package. These packages provide high system bit densities and are compatible with commonly used automatic testing and insertion equipment.

ICC1, ICC3, ICC4 and ICC6 and ICC7 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 100 s is required after power-up followed by 8 RAS-only-refresh 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. 6) AC measurements assume tT = 5 ns. 7) VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Also, transition times are measured between VIH and VIL. 8) Measured with the specified current load and 100 pF at Voh = 2.0 V and Vol = 0.8 V. 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 CAS leading edge in early write cycles and to WRITE leading edge in Read-Modify-Write cycles. 17) When using Self Refresh mode, the following refresh operations must be performed to ensure proper DRAM operation: If row addresses are being refresh in an evenly distributed manner over the refresh iterval using CBR refresh cycles, then only one CBR cycle must be performed immediatly after exit from Self Refresh. If row addresses are being refresh in any other manner (ROR - Distributed/Burst or CBR-Burst) over the refresh interval, then a full set of row refreshed must be performed immediately before entry to and immediatey after exit from Self Refresh Semiconductor Group 72 HYB 3164(5)400J/T-50/-60 16M x 4-DRAM tRC tRAS RAS V IH VIL tCSH V IH VIL tRAD tASR Address V IH VIL tRAL tCAH tASC tASR Column Address Row Address Row Address tRCH tRAH tRCS WRITE OE tRRH V IH VIL tAA tOEA V IH VIL tCDD tDZC tODD tDZO V I/O1-I/O4 IH (Inputs) V IL tCAC tOFF tCLZ V I/O1-I/O4 OH (Outputs) V OL Hi Z tOEZ Valid Data Out tRAC “H” or “L” Read Cycle Semiconductor Group tCRP tRSH tCAS tRCD CAS tRP 73 Hi Z HYB 3164(5)400J/T-50/-60 16M x 4-DRAM tRC tRAS RAS V IH VIL tCSH tRCD tRSH tCAS V IH CAS VIL tRAD tASR Address V IH VIL tASR Column Address Row Address tCWL tWCS t WP V IH VIL tWCH V IH VIL tDS tDH V I/O1-I/O4 IH (Inputs) V IL Valid Data In V I/O1-I/O4 OH (Outputs) V Hi Z OL “H” or “L” Write Cycle (Early Write) Semiconductor Group .
