General Description
Apacer 78.A1GNL.4010B is a 256M x 64 DDR4 SDRAM (Synchronous DRAM)
DIMM. This high-density memory module consists of 4 pieces 256M x 16 bits
with 2 banks DDR4 synchronous DRAMs in FBGA packages and a 4K Bits
EEPROM. The module is a 288-pins dual in-line memory module and is
intended for mounting into a connector socket. The following provides general
specifications of this module.

Notes:
1.
Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and 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.
2.
VDD and VDDQ must be within 300 mV of each other at all times; and VREFCA must be not greater than 0.6 x
VDDQ, When VDD and VDDQ are less than 500 mV; VREF may be equal to or less than 300 mV

TOPER
Notes:
1.
Operating Temperature TOPER is the case surface temperature on the center / top side of the DRAM. For
measurement conditions please refer to the JEDEC document JESD51-2.
2.
The Normal Temperature Range specifies the temperatures where all DRAM specifications will be supported.
During operation, the DRAM case temperature must be maintained between 0℃ - 85℃ under all operating
conditions.
3.
Some applications require operation of the DRAM in the Extended Temperature Range between 85℃ and 95℃
case temperature. Full specifications are guaranteed in this range, but the following additional conditions apply:
a.
Refresh commands must be doubled in frequency, therefore reducing the Refresh interval tREFI to 3.9 µs.
It is also possible to specify a component with 1X refresh (tREFI to 7.8µs) in the Extended Temperature
Range. Please refer to the DIMM SPD for option availability
b.
If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either
use the Manual Self-Refresh mode with
Extended Temperature Range capability (MR2 A6 = 0b and
MR2 A7 = 1b), in this case IDD6 current can be increased around 10~20% than normal Temperature
range.
