MULTIPLE PERFORMANCE MODE MEMORY SYSTEM
First Claim
1. A method for controlling a memory, comprising:
- receiving an input at the memory;
if the input comprises a first input, configuring the memory to a first operation mode, the first operation mode providing a first write performance level and a first storage capacity; and
if the input comprises a second input, configuring the memory to a second operation mode, the second operation mode providing a second write performance level and a second storage capacity;
wherein;
the first write performance level is lower than the second write performance level;
the first storage capacity is larger than the second storage capacity; and
the first operation mode and the second operation mode store a same number of bits per cell in the memory.

Abstract
A method and system for controlling a write performance level of a memory is disclosed. The method includes receiving an input at the memory, and configuring the memory to an operation mode providing a write performance level and a storage capacity. The input may specify a storage capacity, a working area capacity, a write performance level, and/or a ratio of the storage capacity to the working area capacity. A desired write performance level may be set by receiving a software command or hardware setting. The storage capacity may be varied depending on whether the memory device has been formatted. As the storage capacity decreases, working area capacity of the memory device increases and write performance increases. Conversely, as the storage capacity increases, working area capacity decreases and write performance decreases.

23. A method for controlling a memory, comprising:
-
receiving an input at the memory; if the input comprises a first input, configuring the memory to a first ratio; and if the input comprises a second input, configuring the memory to a second ratio; wherein; the memory comprises a total capacity; the first ratio comprises a ratio of a first storage capacity to a first working area capacity, the first working area capacity less than or equal to the first storage capacity subtracted from the total capacity; the second ratio comprises a ratio of a second storage capacity to a second working area capacity, the second working area capacity less than or equal to the second storage capacity subtracted from the total capacity; and the first ratio is higher than the second ratio. - View Dependent Claims (24, 25, 26, 27)
