3D NAND [Permalink]

[Hardware] 

A stack of multiple layers of NAND memory cells.

64B/66B [Permalink]

[Data Communication] 

An algorithm for encoding data for transmission in which each 64-bit data word is converted to a 66-bit transmission character.

Each transmission character is prefixed with either binary "01" or binary "10". This, combined with scrambling, gives the signal desirable engineering properties, yet incurs a much lower overhead than the traditional 8b/10b encoding.

8B/10B encoding [Permalink]

[Data Communication] 

An algorithm for encoding data for transmission in which each eight-bit data byte is converted to a 10-bit transmission character.

8B/10B encoding is used in transmitting data on Fibre Channel, ESCON, Gigabit Ethernet, and Serial Attached SCSI. It supports continuous transmission with a balanced number of ones and zeros in the code stream and detects single bit transmission errors.
