Title:
エミュレート電気的消去可能（ＥＥＥ）メモリおよび動作方法
Document Type and Number:
Japanese Patent JP5787451
Kind Code:
B2
Abstract:
A system has an emulation memory having a plurality of sectors for storing information. A controller calculates a number of addresses used divided by a number of valid records in a predetermined address range of the emulation memory. An amount of remaining addresses in a currently used space of the emulation memory which have not been used to store information is calculated. A determination is made whether the calculation is greater than a first predetermined number and whether the amount of remaining addresses is greater than a second predetermined number. If both the fraction is greater than the first predetermined number and the amount of remaining addresses is greater than the second predetermined number, any subsequent update requests are responded to using the currently used space of the emulation memory. Otherwise a compression of the emulation memory is required by copying valid data to an available sector.
