DATA ACCESS MANAGEMENT APPARATUS AND DATA ACCESS MANAGEMENT METHOD

摘要

The disclosure provides a data access management method and a data access management apparatus which includes an enabling signal generating unit for generating an enabling signal according to a processing signal, a power supplying unit for generating a voltage signal according to the enabling signal, at least a first storage unit for storing a plurality of pieces of data and staying in a standby state or a disable state according to the voltage signal, and a first processing unit. Each piece of data respectively has an access time. The first processing unit calculates a non-access proportion of the data not been accessed for a preset time, according to the access times and then determines whether the non-access proportion is larger than a preset proportion, to generate the processing signal for controlling the at least storage unit to stay in the disable state or the standby state.

主权项

1. A data access management apparatus, comprising:
an enabling signal generating unit configured to generate an enabling signal according to a first processing signal; a power supplying unit coupled with the enabling signal generating unit and configured to receive the enabling signal to generate a voltage signal; at least one first storage unit coupled with the power supplying unit and configured to store a plurality of pieces of data and work in a standby state or a disable state according to the voltage signal, wherein each piece of the data has an access time; and a first processing unit coupled with the at least one first storage unit and the enabling signal generating unit and configured to read the access times to calculate a non-access proportion of the data not been accessed for a preset period, and determine whether the non-access proportion is larger than a preset proportion, wherein when the non-access proportion is larger than the preset proportion, the first processing unit generates the first processing signal for controlling the at least one first storage unit to stay in the disable state; and when the non-access proportion is not larger than the preset proportion, the first processing unit generates the first processing signal for controlling the at least one first storage unit to stay in the standby state.
