Aspects of a storage device including a memory and a controller are provided which simplify controller management of logical and physical meta-dies and meta-blocks by allowing a logical meta-die to be mapped to multiple physical meta-dies. The memory includes first dies grouped in a first physical meta-die and second dies grouped in a second physical meta-die. The physical meta-dies each include physical meta-blocks. The controller maps a logical meta-die to the first physical meta-die and the second physical meta-die. The controller may also map logical meta-blocks of the logical meta-die to the physical meta-blocks. For instance, the controller may associate a first logical metablock of the logical meta-die to the first physical meta-die and a second logical metablock of the logical meta-die to the second physical meta-die. As a result, firmware complexity in managing meta-dies and meta-blocks may be reduced compared to one-to-one logical-to-physical meta-die mapping approaches.

Simplified high capacity die and block management

A controller for a writable optical media is presented. The controller includes a write control sequencer that monitors the transmission of data from a host device to the writable optical media without continuous supervision from a microcomputer. The write control sequencer monitors and controls data flow in response to descriptors which are loaded into the controller prior to the transfer by a microprocessor.
