What Is HBM2 Memory
What does HBM mean?HBM2refers toHigh Bandwidth Memory 2. you’re free to often find the HBM2 memory on Samsung, AMD, and SK Hynix.
Certainly, it is also utilized onserver,high-performance computing and networking, as well asclient space.
The HBM2 offers great performance/watt and has a low power consumption.
HBM2 benefits a lot of people who would like to get the maximum bandwidth especially in a power-constrained environment.
However, HBM2 doesnt leave much space for RAM to work in consumer space.
With the development of technology, HBM2 also develops many versions.
At present, there are 3 available HBM2 versions on the market.
They are JESD235C, JESD235B, and JESD235A.
The newly updated version JESD235C can support faster speeds as high as 3.2Gbps/pin.
It pushes the highest speed for the whole stack of HBM2 memory to 410GB/sec during the process.
Manufacturers have been preparing for upgrade for a long time.
For example, Samsung has made related declarations about their Flashbolt HBM2 memory.
Look into the latest HBM2 version JESD235C.
The latest update even keeps a single stack of HBM2 that makes it quite competitive on the bandwidth front.
Considering from the aspect of cost and capacity, HBM3 memory is still a premium memory technology.
This size allows a 4-stack configuration to get up to 96GB memory.
Generally speaking, HBM utilizes less power but offers high bandwidth than on DDR4 orGDDR5memory that have smaller chips.
This feature seems very attractive to graphics card vendors.
The working principle of HBM is to stack the memory chips vertically on top of one another.
These chips are connected through through-silicon vias and micro-bumps.
These updates will not be the ends of HBM forever.
Though it is not available at present, the HBM3 standard is under discussion.
Besides, you are also aware of the development of HBM in the coming years.
Here comes the end of the post.
