Abstract

A method comprising storing data in a first memory that includes a first portion that has read-only access during a normal mode of operation; and during a update mode of operation: copying at least one data structure from the first memory to a second memory where it is available for use during the update mode; and updating data in the first portion of the first memory.

Claims

1. A method comprising:

storing data in a first memory that includes a first portion that has read-only access during a normal mode of operation; and

during an update mode of operation;

copying at least one data structure from the first memory to a second memory where it is available for use during the update mode; and

updating data in the first portion of the first memory.

2. A method as claimed in claim 1, wherein the at least one data structure is an executable file that provides an application during the update mode.

3. A method as claimed in claim 1, further comprising enabling a user to specify one or more data structures for copying to the second memory during the update mode.

4. A method according to claim 1, further comprising, during the update mode, preventing access to the first memory other than for said copying and updating.

10. A method according to claim 1, wherein the first section of the first memory has one or more partitions.

37. A method according to claim 10, wherein updating data in the first section of the first memory, comprises receiving update package(s) and updating data in selected portions of the first section of the first memory, where the update package(s) include data to be written to the selected portions of the first section of the first memory.

38. A method according to claim 37, wherein the at least one data structure is dependent upon the update package(s).

39. A method according to claim 1, wherein the step of copying further comprises copying an update application to the second memory for restarting the update procedure if it is terminated.

5-9. -9. (canceled)

11-36. -36. (canceled)

40. A computer program comprising computer program instructions for:

changing a mode of operation of a device from a normal mode of operation in which a section of a first memory has read-only access to an update mode of operation in which the section of the memory is updatable; and

during the update mode of operation, enabling copying of at least one data structure from a first memory to a second memory and updating of data in the section of the first memory, enabling a user to specify the one or more data structures for copying to the second memory, preventing access to the first memory, copying an update application to the second memory for restarting the update procedure if it is terminated.

41. An apparatus comprising:

a first memory that includes a first section configured for read-only access during a normal mode of operation;

a second memory configured to store data for use during an update mode of operation; and

an update controller arrangement configured to control the transition from the normal mode to the update mode, to enable the transfer of data for use during the update mode from the first memory to the second memory and enable updating of at least a part of the first section of the first memory during the update mode.

42. An apparatus according to claim 41 wherein the update controller arrangement comprises a processor and memory access controller for the first memory.

43. An apparatus according to claim 41, wherein the data is an executable file that provides an application during the update mode.

44. An apparatus according to claim 41, further configured to during the update mode prevent access to the first memory other than for said transferring of data during the update mode from the first memory to the second memory and for said updating of at least a part of the first section of the first memory during the update mode.

45. An apparatus according to claim 41, further configured to receive update package(s) identifying the at least a part of the first section of the first memory.

46. An apparatus according to claim 45, wherein the data for use during the update mode is dependent upon update package(s), where the update package(s) include data to be written to the at least a part of the first section of the first memory.

47. An apparatus according to claim 41, wherein the update controller arrangement is configured to enable the transfer of an update application to the second memory for restarting the update procedure if it is terminated.

48. An apparatus according to claim 41, wherein the first memory is a NAND type flash memory.

49. An apparatus according to claims 41, wherein the first memory has a second section for storing data that is accessible for reading and writing during the normal mode of operation.

50. An apparatus according to claim 41, wherein the second memory is a random access type memory.

51. An apparatus according to claim 41 comprising a mobile terminal.
