Description
M1U1G64DS8HB1G and M1Y1G64DS8HB1G (green part) are unbuffered 200-Pin Double Data Rate (DDR) Synchronous DRAM Unbuffered
Dual In-Line Memory Module (UDIMM) and are organized as two ranks of 64Mbx64 high-speed memory array using sixteen 64Mx8 DDR
SDRAMs TSOP packages. M1U51264DS88B1G and M1Y51264DS88B1G are unbuffered 200-Pin DDR Synchronous DRAM UDIMM and are
organized as a single rank of 64Mbx64 high-speed memory array using eight 32Mx16 DDR SDRAMs TSOP packages. M1U25664DSH4B1G
and M1Y25664DSH4B1G are unbuffered 200-Pin DDR Synchronous DRAM UDIMM and are organized as a single rank of 32Mbx64 high-speed
memory array using four 32Mx16 DDR SDRAMs TSOP packages.
Depending on the speed grade, these DIMMs are intended for use in applications operating up to 200 MHz clock speeds and achieves
high-speed data transfer rates of up to 400 MHz. Prior to any access operation, the device
CAS
latency and burst type/ length/operation type
must be programmed into the DIMM by address inputs and I/O inputs BA0 and BA1 using the mode register set cycle.
The DIMM uses a serial EEPROM and through the use of a standard IIC protocol the serial presence-detect implementation (SPD) can be
accessed. The first 128 bytes of the SPD data are programmed with the module characteristics as defined by JEDEC.

The system clock inputs. All address and command lines are sampled on the cross point of
the rising edge of CK and falling edge of CK. A Delay Locked Loop (DLL) circuit is driven
from the clock inputs and output timing for read operations is synchronized to the input
clock.
Activates the DDR SDRAM CK signal when high and deactivates the CK signal when low.
By deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh
mode.
Enables the associated DDR SDRAM command decoder when low and disables the

Selects which SDRAM bank is to be active.
During a Bank Activate command cycle, A0-A12 defines the row address (RA0-RA12) when
sampled at the rising clock edge.
During a Read or Write command cycle, A0-A9 defines the column address (CA0-CA9)
A0 - A9

when sampled at the rising clock edge. In addition to the column address, AP is used to

-
invoke auto-precharge operation at the end of the Burst Read or Write cycle. If AP is high,
auto-precharge is selected and BA0/BA1 defines the bank to be precharged. If AP is low,
auto-precharge is disabled.
During a Precharge command cycle, AP is used in conjunction with BA0/BA1 to control
which bank(s) to precharge. If AP is high all 4 banks will be precharged regardless of the
state of BA0/BA1. If AP is low, then BA0/BA1 are used to define which bank to pre-charge.

Data and Check Bit input/output pins operate in the same manner as on conventional

Data strobes: Output with read data, input with write data. Edge aligned with read data,
centered on write data. Used to capture write data.
Data Check Bit Input/Output pins. Used on ECC modules and is not used on x64 modules.
The data write masks, associated with one data byte. In Write mode, DM operates as a byte
mask by allowing input data to be written if it is low but blocks the write operation if it is high.
In Read mode, DM lines have no effect. DM8 is associated with check bits CB0-CB7, and is
not used on x64 modules.
Power and ground for the DDR SDRAM input buffers and core logic
Address inputs. Connected to either V

on the system board to configure the Serial

This bi-directional pin is used to transfer data into or out of the SPD EEPROM. A resistor
must be connected from the SDA bus line to V DD to act as a pull-up.
This signal is used to clock data into and out of the SPD EEPROM. A resistor may be
