On December 13th, 2017 at 1.30 pm, “Mobile Main Memories: System and Technology” seminar will be held in D11 Room, as new appointment of HEAP Lab Talks.
Memories are a key component of all computing systems. Just think that last year DRAM market has reached the value of 69B$, out of 400B$ of the whole semiconductor market. Moreover, the market feels a further boost to growth: users are eager of devices with always increasing performance which includes speed, power and capacity.
In order to meet the expected performance growth and to follow the evolving market requirements, main memory system must improve in size, technology, efficiency, cost, and management algorithms.
But mainstream memory technologies are reaching their scaling limits. Thus it’s paramount to work on different approaches: modify how the system uses main memory, change the architecture of memory devices, enable alternative technologies (emerging memories like 3D XPoint), and add functionalities to the memory systems (like error correcting codes and security primitives).
In this talk we’ll focus on mobile memories, which account for almost 50% of DRAM bits.
In particular we’ll review the memory hierarchy in the mobile systems, discuss mobile DRAM devices (like LPDD4), describe the main DRAM scaling limits, and look at what is coming next.
