SSDs can now store 1 terabyte of data by stacking memory cells 100 layers tall, copied 40,000 columns across, and 50,000 rows down, using charge trap flash technology to trap different levels of electrons.
Insights
- SSDs can hold 1 terabyte of data through charge trap flash cells storing 3 bits each, requiring intricate stacking of 100 layers, 40,000 columns, and 50,000 rows to create a 3D array.
- The process of achieving a terabyte of storage capacity in SSDs involves meticulous duplication of the 3D array onto both sides of the microchip, repeated 8 times for compact integration.

"1TB SSDs: Microchip Stores 3 Weeks Movies"
- Solid-state drives (SSDs) can store 1 terabyte of data in a microchip, equivalent to 3 weeks of non-stop movie and TV show binging, achieved through individual memory cells called charge trap flash storing 3 bits of information by trapping different levels of electrons.
- To reach a terabyte of storage capacity, memory cells are stacked 100 layers tall, copied 40,000 columns across, and 50,000 rows down, forming a 3D array of charge trap flash cells and control gates, which is then duplicated onto the other side and repeated 8 times to fit into a single microchip.
