Impacts of the RAM Shortage

Starting in late 2025, the world began experiencing a big shortage of memory chips used in the manufacture of smartphones, computers, and other consumer electronics. The shortage has been caused by chip makers across the industry deciding to manufacture more lucrative chips for AI data centers. As an example, during the last year, we saw Micron, Samsung, and SK Hynix stop making RAM for consumer devices in favor of AI chips.

Random access memory, or RAM, is a crucial component in devices like smartphones, computers, and game consoles. RAM chips are what allow a computer to perform functions like keeping multiple tabs open in  a browser,

In the fourth quarter of last year, the demand for RAM chips exceeded supply by 10%, and the shortage is quickly growing. By the end of 2025, the price for RAM increased by 50%, and the supply chain delays to get chips suddenly slowed to a crawl. If an electronics factory wants chips sooner, they’re being forced to pay a premium price and pre-pay for a large supply. The shortage is expected to last at least into 2027. A few companies, like ChangXin Memory Technology and Yangtze Memory Technologies Corp. have stepped up to enter the consumer RAM market. There are predictions that RAM prices will increase at least 60% this year, with specialty chips possibly doubling or tripling in price.

This is bad news for the broadband industry since the price of computers and smartphones will climb, likely out of the reach of the budgets of many households. This is going to increase the cost of all of the network electronics used for fiber, cable HFC, and wireless networks.

This is bad news for the nonprofits that have been refurbishing used computers and smartphones. One important part of many upgrades is to increase RAM capacity for old computers to be able handle new web needs. If RAM prices double, these entities will not be able to help nearly as many people. The problem will be made worse since small buyers of RAM will probably be the ones seeing the biggest price increases.

Digitunity recently published an article that estimates that 32.9 million people can’t access broadband from due to the lack of a computer. That’s about 10% of households, a number that compares with other estimates of the homes with broadband.

More expensive computers will hurt broadband adoption, and that hurts the public and the economy. People are increasingly reliant on access to broadband. The federal government, and many state and local governments, are eliminating the ability to communicate with the government by anything other than web portals. Federal services of all sorts, like veterans benefits and Social Security, are moving online.

The IRS and many states expect taxpayers to file tax returns using online software. This software is difficult to navigate with a smartphone, as are many other government portals. The IRS and other federal agencies will also no longer issue paper checks, forcing people to have an electronic way to receive and access payments from the government.

FEMA announced last year that anybody affected by a disaster must make a claim online, which is a particularly ironic requirement for folks who might have just lost a home due to a flood, tornado, or hurricane. For anybody who has ever dealt with a disaster result, there is a mountain of communication needed to push a claim through to the finish line.

People in rural areas increasingly need to use telemedicine as rural hospitals and clinics continue to fail and close.

A computer at home is vital for working from home or taking college and other classes online. These are also tasks that can’t easily be done by smartphone.

A Rural Cellular Story

I was looking through the FCC cellular map in Buncombe County, North Carolina, where I live. For those not fully familiar with the FCC broadband maps, the agency publishes two maps: the more familiar one that shows broadband coverage and a second that shows cellular coverage. You can toggle between the two maps at the FCC’s map website.

It struck me while looking at the details in the maps that rural cellular coverage is changing, and not in a good way. I started by looking at a small section of the county that is on the outer fringe of where the Asheville outer suburbs turn rural. According to the FCC cellular map, the area I selected has the following cellular coverage:

These two tables tell me the following:

  • AT&T and Verizon have some 4G coverage. But the Verizon coverage is likely very weak since they don’t claim it will work in a moving vehicle. While AT&T claims its 4G coverage will work in a moving vehicle, it’s curious that AT&T doesn’t have 5G. This tells me that the AT&T signal is also likely weak since it is outside the 5G coverage area.
  • The only carrier claiming relatively solid 5G (35/3 Mbps) is Project Genesis, which is EchoStar. The company has exited the facility-based cellular business and is in the process of dismantling cell sites.
  • T-Mobile claims both 4G and 5G for outdoor cellular coverage, but doesn’t claim it can work in a moving vehicle, meaning the coverage is also probably weak.
  • The last carrier listed is UScellular, which claims 7/1 speeds on 5G, but doesn’t claim to be able to provide coverage in vehicles. UScellular was purchased by T-Mobile, and the rumor is that any UScellular towers that already duplicate T-Mobile coverage are likely to be decommissioned.

The bottom line is that this particular neighborhood has weak cell coverage. The only carrier that claimed to be able to deliver 5G to a moving vehicle is now out of business.

I picked this neighborhood at random, but I think I would find the same story in most of the areas on the fringe of the metropolitan area. The coverage in areas that are completely rural is worse. The story I gleaned from this neighborhood is troublesome for several reasons.

  • The folks who live here don’t have a lot of options. The only carrier that might work in the way people need cellular to work is AT&T, but this neighborhood is outside the AT&T 5G coverage, and the 4G coverage is likely weak.
  • It looks like decent coverage was finally becoming available from EchoStar, but that’s now gone.
  • The speeds shown in the table are for outdoor coverage, and speeds inside homes are typically half of outdoor speeds.
  • When you look at the details in the FCC cellular map you quickly understand how the advertised national footprints of the big carriers are exaggerated.
  • The bad news is that the FCC considers this neighborhood to be served by cellular. That means if the FCC finally launches the 5G Fund for Rural America, this neighborhood will not be considered for funding to add a new cell tower.
