Method for writing data into flash memory apparatus, flash memory apparatus, and storage system

A flash memory apparatus for controlling storage of data, comprising:

• a plurality of blocks configured to store data, wherein each block includes a plurality of pages;
• and
• a controller configured to receive first target data;
• identify a first block to store the first target data, wherein an available capacity of the first block is less than a size of the first target data, wherein the available capacity of the first block is determined by subtracting a reduced capacity of the first block from a total capacity of the first block, wherein the reduced capacity of the first block is caused by one or more unavailable pages in the first block;
• obtain a overflow part of the first target data by writing the first target data into the first block;
• determine a second block that has stored data but is not full;
• and
• write the overflow part of the first target data into the second block.

A method for a flash memory apparatus controlling storage of data, wherein the flash memory apparatus includes a controller and a plurality of blocks, and wherein each block includes a plurality of pages, the method performed by the controller comprising:

• receiving first target data;
• identifying a first block to store the first target data, wherein an available capacity of the first block is less than a size of the first target data, wherein the available capacity of the first block is determined by subtracting a reduced capacity of the first block from a total capacity of the first block, wherein the reduced capacity of the first block is caused by one or more unavailable pages in the first block;
• dividing the first target data into two parts, wherein a size of a first part of the first target data is equal to the available capacity of the first block, and wherein a size of a second part of the first target data is equal to the size of the first target data minus the size of the first part of the first target data;
• determining a second block that has stored data but is not full;
• writing the first part of the first target data into the first block;
• and
• writing the second part of the first target data into the second block.
