Universal Flash Storage (UFS) was created for mobile applications and computer systems requiring high performance and low power consumption. These systems typically use embedded Flash based on the JEDEC standard eMMC. UFS was defined by JEDEC as the evolutionary replacement for eMMC offering significantly higher memory bandwidth. The standard builds on existing standards such as the SCSI command set, the MIPI Alliance M-PHY and UniProSM as well as eMMC form factors to simplify adoption and development.
Tapeout marks the transfer of SoC's database from design team to mask preparation team which could be within the organization or an interface team in an external fabrication house. This design database which could be a GDS, is to be worked upon with complex Boolean operations, sizing, and, optical proximity corrections (OPC). These post tapeout operations are performed by mask preparation team or an external interface team. The output of this exercise is called MEBES database which is an ensemble of all the masks to be manufactured in the fabrication house.
