Random read/write performance of probe storage memory devices

Abstract

Current probe-type memory architecture assumes that the minimum chunk of data that a probe tip can access is one entire track and perhaps only four out of five-thousand, for example, probes participate in the access thereby degrading performance. By subdividing the track into D finer chunks or data zones, D times more probes can cooperate to read out the data, hence increasing the data throughput by Dx. Each tip now only scans approximately one Dth of the track and hence the scan time is reduced by a factor D, while D probes are being utilized in parallel.
