Absolute Maximum DC Ratings
Note :
1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and
2. Storage Temperature is the case surface temperature on the center/top side of the DRAM. For the measurement conditions, please refer to JESD51-2
AC & DC Operating Conditions
Recommended DC Operating Conditions (SSTL - 1.8)
Note : There is no specific device V
1. The value of V
2. Peak to peak AC noise on V
3. V
4. AC parameters are measured with V
256MB, 512MB, 1GB Unbuffered SODIMMs
functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect reliability.
