• Manufacturer Part Number: k4t1g084qm-zcd5
• Description: 1gb M-die Ddr2 Sdram Ddr2 Sdram
• Manufacturer: Samsung Semiconductor, Inc.

1Gb M-die DDR2 SDRAM
Notes :
1. IDD specifications are tested after the device is properly initialized
2. Input slew rate is specified by AC Parametric Test Condition
3. IDD parameters are specified with ODT disabled.
4. Data bus consists of DQ, DM, DQS, DQS\, RDQS, RDQS\, LDQS, LDQS\, UDQS, and UDQS\. IDD values must be met with all combi-
5. Definitions for IDD
For purposes of IDD testing, the following parameters are utilized
Detailed IDD7
The detailed timings are shown below for IDD7.
Legend: A = Active; RA = Read with Autoprecharge; D = Deselect
IDD7: Operating Current: All Bank Interleave Read operation
All banks are being interleaved at minimum t RC(IDD) without violating t RRD(IDD) using a burst length of 4. Control and address bus
inputs are STABLE during DESELECTs. IOUT = 0mA

nations of EMRS bits 10 and 11.
LOW is defined as Vind VILAC(max)
HIGH is defined as Vin tVIHAC(min)
STABLE is defined as inputs stable at a HIGH or LOW level
FLOATING is defined as inputs at VREF = VDDQ/2
SWITCHING is defined as:
signals, and
inputs changing between HIGH and LOW every other data transfer (once per clock) for DQ signals not including
inputs changing between HIGH and LOW every other clock cycle (once per two clocks) for address and control
masks or strobes.
