Claim 0:
1. A DRAM (dynamic random access memory) device, comprising:
a circuit substrate, at least one DRAM chip being disposed on the circuit substrate;
a light emitting element disposed on the circuit substrate and coupled to the circuit substrate;
a first light-permeable thermal dissipation element disposed on the circuit substrate, wherein the first light-permeable thermal dissipation element includes:
a first light guiding portion,
a first light uniform portion connected to the first light guiding portion, and
a first joint portion disposed on the first light guiding portion;

a first light blocking element disposed between the first light-permeable thermal dissipation element and the circuit substrate, and disposed on the first light-permeable thermal dissipation element;
a second light-permeable thermal dissipation element disposed on the circuit substrate; and
a second light blocking element being disposed between the second light-permeable thermal dissipation element and the circuit substrate,
wherein the second light blocking element is disposed on the second light-permeable thermal dissipation element,
wherein the first light-permeable thermal dissipation element and the first light blocking element are disposed at one side of the circuit substrate, and the second light-permeable thermal dissipation element and the second light blocking element are disposed at another side of the circuit substrate,
wherein the second light-permeable thermal dissipation element includes:
a second light guiding portion,
a second light uniform portion connected to the second light guiding portion, and
a second joint portion disposed on the second light guiding portion and corresponding to the first joint portion,

wherein a light generated by the light emitting element includes a first incident light projected to the first light guiding portion and a second incident light projected to the second light guiding portion, a first scattered light being generated after the first incident light has passed through the first light guiding portion and the first light uniform portion, and a second scattered light being generated after the second incident light has passed through the second light guiding portion and the second light uniform portion.
