• Manufacturer Part Number: k4t51163qi-hpf7
• Description: 512mb I-die Ddr2 Sdram
• Manufacturer: Samsung Semiconductor, Inc.

Note :
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 combinations of EMRS
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 tRC(IDD) without violating tRRD(IDD) and tFAW(IDD) using a burst length of 4. Control and address bus
inputs are STABLE during DESELECTs. IOUT = 0mA
