BiCS FLASH™ | TLC & QLC​

KIOXIA‘s Scalable BiCS FLASH™ 3D Flash Memory Technology Boosts Memory Capacity to Highest Level Yet Achieved

KIOXIA’s BiCS FLASH™ is a three-dimensional (3D) vertical flash memory cell structure. This structure enables it to surpass the capacity of 2D (planar) flash memory. KIOXIA’s TLC 3-bit-per-cell 1Tb (128GB*1) BiCS FLASH™, an industry first*2, enhances the reliability of write/erase endurance while boosting write speeds. The company also offers a 1.33Tb BiCS FLASH™ device that features 4-bit-per-cell, quadruple-level-cell (QLC), technology. It's the first 3D flash memory device to do so.*3

Key Features of KIOXIA BiCS FLASH™ 3D Flash Memory Technology

  • Higher storage density per die than conventional Flash Memory
  • Higher Read/Write speed performance
  • Higher Reliability than 2D (planer) NAND
  • Low Power Consumption

TLC (Triple-Level Cell) and QLC (Quadruple-Level Cell) Technology

KIOXIA’s fifth generation BiCS FLASH™ offers 512 gigabit (Gb) 3-bit-per-cell, triple-level cell (TLC) and higher density QLC technology enables larger die capacity. KIOXIA achieved the industry’s largest capacity*4 per die of 1.33 terabit (Tb), and a 16-die stacked architecture can realize an unparalleled capacity of 2.66 terabyte (TB) in a single package.

Leading the Drive Toward Greater Memory Density and Efficiency

KIOXIA was the first industry player to envision and prepare for the successful migration of SLC technology to MLC, from MLC to TLC, and now from TLC to QLC.

KIOXIA’s QLC technology is ideal for applications requiring high density, lower cost storage solutions. Today’s QLC reduces the footprint with the highest density available in a single package.

KIOXIA QLC Technology Enables Highest Density Flash in a Single Package.
  1. Product density is identified based on the density of memory chip(s) within the Product, not the amount of memory capacity available for data storage by the end user. Consumer-usable capacity will be less due to overhead data areas, formatting, bad blocks, and other constraints, and may also vary based on the host device and application. For details, please refer to applicable product specifications. The definition of 1Gb = 230 bits = 1,073,741,824 bits. The definition of 1GB = 230 bytes = 1,073,741,824 bytes.
