A first operation identifier is assigned to a current operation directed to a memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier. It is determined whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier. A latest flag is updated to indicate that the first entry is a latest operation directed to an address (1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or (2) in response to determining to determining that the current operation does not collide with a prior operation.

Handling operation collisions in a non-volatile memory

A first operation identifier is assigned to a first operation directed to a memory component, the first operation identifier having an entry in a first data structure that associates the first operation identifier with a first plurality of buffer identifiers. It is determined whether the first operation collides with a prior operation assigned a second operation identifier, the second operation identifier having an entry in the first data structure that associates the second operation identifier with a second plurality of buffer identifiers. It is determined whether the first operation is a read or a write operation. In response to determining that the first operation collides with the prior operation and that the first operation is a read operation, the first plurality of buffer identifiers are updated with a buffer identifier included in the second plurality of buffer identifiers.

Exemplary methods, apparatuses, and systems include firmware for the non-volatile storage device, during boot up, dynamically allocating volatile memory to a plurality of storage management components. The allocation includes detecting an indicator of a total amount of volatile memory to be allocated to the storage management components. The firmware maps the indicator to a first amount of volatile memory to allocate to a first set of one or more components and allocates the first amount of the volatile memory to the first set of components. The firmware allocates remaining volatile memory to a flash translation layer.
