bit density
The number of bits that can be stored within a given physical area. See bpi.

A Memory Bit
This is one storage cell in an earlier 16-megabit DRAM memory chip. Although minuscule in overall capacity compared to today's memory, there were 16,777,216 of these cells in the chip, which was only a quarter of an inch square.

The impressive transfer speed, fast data searching, write-once read-many technology, increased bit density and long durable life of Sony LTO-3 tape format secures the clients'' investments.
For instance a PRML (Partial Response Maximum Likelihood) channel interprets the recorded transitions in a different way by partial amplitude sampling in order to increase the bit density using somewhat lower magnetic transition densities than in straight peak detect channels as illustrated.
MoSys' industry-leading 36-Mbit SRAM offers the highest available bit density and lowest power consumption.
