Something we always do before going to bed! It is none other than uploading posts on social media. A social media fanatic, Suyeon, is trying to share her eventful day on her social media, where she reviews the photos she has taken throughout the day to share with others. However, this time, she cannot see a single photo of the thousands of photos she has on her smartphone. Suyeon, panicking, opens the social media app, which is also irresponsive. Which semiconductor disappeared this time?
Photos are memories! Semiconductor memory, here to save your memories
Her smartphone photo album and social media apps are not working because semiconductor memories have disappeared. Among semiconductor memories, there are fast and volatile memory, DRAM, and large-capacity and slower but non-volatile NAND flash. On smartphones, we have the UFS, a type of mobile NAND flash, as the embedded storage. And when we want to use a smartphone app to make simple tweaks in our photos, we use the DRAM as the extra memory in the central processing unit.
With the semiconductor memory gone, it is no surprise that social media apps suddenly do not work, is it? Since there is no way to locate the uploaded images, the app cannot do anything. In particular, as the videos and images uploaded on social media have gotten bigger in size in the recent times, the role of semiconductor memory is becoming increasingly important for saving data.
This was college student Suyeon’s day without semiconductors! Did you enjoy it? It was surprisingly easy to find semiconductors working all around us. Semiconductors are so closely related to us! We will be back with more intriguing and educational stories, so stay tuned.
