HYM64(72)V4005/45GU-50/-60
4M x 64/72 DRAM Module
The HYM64(72)V4005/45GU-50/-60 are industry standard 168-pin 8-byte Dual In-Line Memory
Modules (DIMMs) which are organized as 4M x 64 and 4M x 72 high speed memory arrays
designed with EDO DRAMs for non-parity and ECC applications. 2k refresh with 11 / 11 addressing
and 4k refresh modules with 12 / 10 addressing are available. The DIMMs use sixteen 4M x 4 EDO
DRAMs for the 4M x 64 organisation and eighteen 4M x 4 DRAMs for the 4M x 72 organisation, both
in TSOPII packages. Decoupling capacitors are mounted on the PC board.
The DIMMs use optional serial presence detects implemented via a serial E 2PROM using the two
pin I2C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128
bytes of serial PD data are available to the customer.
All 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133,35 mm long spacesaving footprint.

HYM64(72)V4005/45GU-50/-60
4M x 64/72 DRAM Module
Notes:
1) All voltages are referenced to VSS.
2) ICC1, ICC3, ICC4 and ICC6 depend on cycle rate.
3) ICC1 and ICC4 depend on output loading. Specified values are obtained with the output open.
4) Address can be changed once or less while RAS = Vil. In case of ICC4 it can be changed once or less during
a hyper page mode (EDO) cycle
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 the internal refresh counter,
a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required.
6) AC measurements assume
tT = 2 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 the specified current load and 100 pF at Vol = 0.8 V and Voh = 2.0 V. Access time is determined
by the latter of t RAC, tCAC, tAA,tCPA ,tOEA. t CAC is measured from tristate.
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.), tOEZ (max.) define the time at which the output achieves the open-circuit conditions and are not
referenced to output voltage levels. tOFF is referenced from the rising edge of RAS or CAS, whichever occurs
last.
13) Either tDZC or tDZO must be satisfied.
14) Either tCDD or tODD must be satisfied.
15) 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 I/O will contain data read from the selected cells. If neither of the above
sets of conditions is satisfied, the condition of I/O (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.

HYM64(72)V4005/45GU-50/-60
4M x 64/72 DRAM Module
Serial Presence Detects:
A serial presence detect storage device -- EEPROM 24C02 -- is assembled on to the module.
Information about the modul confuguration, speed, etc. is written into the EEPROM device during
module production using a serial presence detect protocol ( I 2C synchronous 2-wire bus).
