Abstract:
A solid state storage device and method are provided. Multiple blocks are configured as storage memory for a solid state storage device, and each block includes multiple pages. A controller is configured to operate the solid state storage device. A free block of the multiple blocks is assigned a marker level by the controller. For a particular page of the multiple pages, each particular page of data is written to a block of the multiple blocks with a marker level corresponding to a level of dynamicity calculated by the controller for that particular page.
