A lightweight directory access protocol workflow management system. The invention converts a logical process into a reusable Lightweight Directory Access Protocol (LDAP) directory representation. The directory representation is a hierarchical tree structure where each process element in the process is represented as an LDAP directory entry and is assigned a unique distinguished name and is stored in a Directory Server database or filesystem. The tree structure of the LDAP representation allows the sharing of LDAP trees or subtrees among users. The LDAP trees and subtrees can be remotely located and distributed among different LDAP servers. Another preferred embodiment of the invention provides a graphical user interface for creating a Workflow process definition which is comprised of process elements: activities; actions; and entry/exit points. The user constructs a Workflow process using the process elements, logically interrelating each activity. Once the Workflow process is defined it is converted into an LDAP directory representation and stored in a Directory Server database or filesystem.

A word line driver is provided for accessing a DRAM cell embedded in a conventional logic process. The DRAM cell includes a p-channel access transistor coupled to a cell capacitor. The word line driver includes an n-channel transistor located in a p-well, wherein the p-well is located in a deep n-well. The deep n-well is located in a p-type substrate. A word line couples the drain of the n-channel transistor to the gate of the p-channel access transistor. A negative boosted voltage supply applies a negative boosted voltage to the p-well and the source of the n-channel transistor. The negative boosted voltage is less than ground by an amount equal to or greater than the threshold voltage of the p-channel access transistor. The deep n-well and the p-type substrate are coupled to ground. The various polarities can be reversed in another embodiment.

Through associating each data partition within a replicated storage domain of networked storage devices with one of multiple secret keys shared with a file manager, a credential is issued from the file manager to a client requesting access to a partition. The credential includes a network address for the partition to which the client is to direct its actions. The storage device periodically confirms with the file manager the validity of the shared secret keys. Through logical process and evaluations applied to issuing the credential and determining the address of the partition to be included in each credential, the file manager may invalidate partitions individually, provide load balancing between access of original and replica partitions, and provide security functions such as isolation of partitions for access by and tracking of unauthorized users, or for testing purposes.
