8 GB and 16 GB
DDR5 DRAM s will be available for servers and mainframes; hopefully, by next year, the capacity of DDR5 RAM will be precisely where DDR4 is today. The standard set by Joint Electron Device Engineering Council (JEDEC) allows manufacturers to design devices featuring a 24 GB, a 32 GB, or a 64 GB capacity, which is exactly four times of current DDR4 capacity.
What is being听covered in this post
This post will give you a brief outline of DRAM and DDR5 technology, evolution, and comparison among various DDR versions, DRAM packaging, market overview, major DRAM vendors,听and a list of suggested reports which can help you with the latest market data and analysis.
Evolution of DRAMs
The evolution of DRAM follows the same course as the development of CPUs.听Currently, microprocessors endeavor for higher core count, improved per-core performance, and greater power efficiency, which sets standards for system memory.听Similarly, over the generations, DRAM's capacity (and high bandwidth) has been increased and power consumption has been reduced.
听
The first generation DRAM was Asynchronous DRAM, in which RAM was not synchronized with the CPU clock. The drawback of that system was that the CPU was not aware of what time data would be available from RAM over input/output bus. The next generation was synchronous DRAM/SDRAM. In this system CPU or memory controller knew after how many cycles data would be available from RAM over a communication bus, in this way memory read and write speed increased. In the next generation, DDR RAM (double data rate RAM) was introduced. In this system data transferred twice during the CPU clock cycle.

Bird's-eye view of DDR Memories: DDR1-DDR5
The DDR1 RAM was released in the year 2000. In comparison to SDRAM, the voltage consumption by DDR1 was reduced to 2.5 volts from 3.3 volts whereas the DDR5 will consume 1.1 volts with a speed of
4.8 Gbps scalable up to at least 6.4 Gbps. The DDR1 RAM transferred data both in rising and falling edge of the CPU clock cycle that is generally termed
2-bit prefetch while DDR5 will have 16-bit prefetch. Chip density range has been increased to 32 Gb in DDR5 which generally memory density of the individual chips on the module. Let us see the comparison snapshot among DDR1, DDR2, DDR3,
DDR4 , and DDR5 in the table given below:

Overview of the packaging of DRAMs
There are two main types of DRAM packaging : single inline memory module (SIMM) and dual inline memory module (DIMM) .听The older generation of DRAM was available in DIP also known as Dual inline package, the next-generation DRAM came with SIMM or Single inline modules in this technology memory chips are soldered in single PCB, hence pins were available on a single side that is why it was called Single inline. The current generation of DRAM comes in DIMM or Dual inline modules; in these pins are available both in front and backside of PCB.
The modules which are used in laptop and notebook are known as SO-DIMM (small outline DIMM) the design of these modules are compact and designed by keeping the available space in the host device. The DRAMs which are being used in mobiles and wearable healthcare devices are known as MDDR/LPDDR or Low power DDR. These Low Power DDR also have generation right from LPDDR1-LPDDR4X. LPDDRs are designed for low power consumption because these are used in smartphones which are having a less powerful battery. Samsung claims its LPDDR5 reaches a pin speed of 6,400 Mbps.
The other type of DRAM is GDDR or Graphics DDR which are used in Media/Graphics Card; it also has its own generation GDDR1-GDDR6. AMD popular Navi 10 GPUs utilize 8 GB of GDDR6 memory.
Global DRAM Market Overview
The global DRAM market is very competitive, and a handful of vendors are concentrated in the APAC region. APAC accounted for the maximum DRAM market share and will continue its market dominance during the next few years. In terms of geographic regions, 听The presence of a number of DRAM manufacturers and OEM suppliers in countries like Taiwan and South Korea is one of the key factors that account for the region鈥檚 dominance in this global market. The easy availability of raw materials and cheap labor make it quite easy for manufacturers to set up their base in the region.
