Abstract
A method and apparatus for dynamic controller buffer management is disclosed. According to certain embodiments, responsive to commands received from a host, a controller may adjust one or more partitions of a controller buffer memory to adjust the size of different types of buffer memory. In some embodiments, preset buffer memory configurations may be applied to the buffer memory to adjust buffer memory allocation based on the current workload. By way of example, when sequential reads are detected, a TRAM buffer size may be increased to provide additional RLA buffers, at the expense of XRAM and/or L2P buffer size. Where operations involving SLC memory is detected, allocation of buffer memory parity buffers of XRAM may be decreased, to provide additional buffer space to L2P.
