  • Method to detect NAND-flash parameters by hardware automatically
    Patent number: 7657696
    Abstract: A method for automatically detecting a plurality of parameters for a NAND-Flash memory. A first step of the method may include generating a plurality of address cycles for the NAND-Flash memory. A second step may set an address number parameter of the parameters based on (i) a first number of the address cycles generated and (ii) a status signal generated by the NAND-Flash memory responsive to the address cycles. A third step generally includes generating at least one read cycle for the NAND-Flash memory after determining the address number parameter. A fourth step may set a page size parameter of the parameters based on (i) a second number of the read cycles generated and (ii) the status signal further responsive to the read cycles.

  • Central dynamic memory manager
    Patent number: 6883082
    Abstract: A circuit generally comprising a memory and a core module is disclosed. The memory may be configured as (i) a first stack having a plurality of index pointers and (ii) a table having a plurality of entries. The core module may be configured to (i) pop a first index pointer of the index pointers from the first stack in response to receiving a first command generated by a first module external to the circuit, (ii) assign a first entry of the entries identified by the first index pointer to the first module, (iii) generate an address in response to converting the first index pointer and (iv) transfer the address to the first module.
