Abstract: A method, non-transitory computer readable medium, and device that assists with reducing memory fragmentation in solid state devices includes identifying an allocation area within an address range to write data from a cache. Next, the identified allocation area is determined for including previously stored data. The previously stored data is read from the identified allocation area when it is determined that the identified allocation area comprises previously stored data. Next, both the write data from the cache and the read previously stored data are written back into the identified allocation area sequentially through the address range.

Abstract translation: 帮助减少固态设备中的存储器碎片的方法，非暂时性计算机可读介质和设备包括识别地址范围内的分配区域以从高速缓存写入数据。 接下来，所确定的分配区域被确定为包括先前存储的数据。 当确定所识别的分配区域包括先前存储的数据时，从识别的分配区域读取先前存储的数据。 接下来，来自高速缓存的写入数据和先前存储的读取数据都通过地址范围顺序写回到所标识的分配区域中。
