摘要:
Apparatus and methods disclose techniques to control access to a memory array. The memory array can be accessed by either a first interface or a second interface. A switch register grants privilege levels, which control access. For example, a high privilege level can grant access and a low privilege level can deny access. A status register indicates when an interface with a high privilege level is busy accessing the memory array.

Subject matter disclosed herein relates to an apparatus comprising memory and a controller, such as a controller which determines block locking states in association with operative transitions between two or more interfaces that share at least one block of memory. The apparatus may support single channel or multi-channel memory access, write protection state logic, or various interface priority schemes.

Various embodiments comprise apparatuses and methods including a method of reconfiguring partitions in a memory device as directed by a host. The method includes managing commands through a first interface controller to mapped portions of a first memory not having an attribute enhanced set, and mapping portions of a second memory having the attribute enhanced set through a second interface controller. Additional apparatuses and methods are described.

摘要:
A sense amplifier may be used to measure voltages and/or currents that represent logic levels stored in memory cells of memory devices. Accuracy and stability of such measurements may be improved by selective switching to isolate sense amplifiers from other portions of a circuit.

A method of managing a multi-level memory device having singularly addressable three-level cells includes storing strings of three bits by coding them in corresponding ternary strings according to a coding scheme and writing each of the ternary strings in a respective pair of three-level cells. Strings of three bits are read by reading respective ternary strings written in respective pairs of three-level cells and decoding each read ternary string in a corresponding string of three bits according to the coding scheme. A pair of adjacent bits, belonging to at least one of a same initial string and two initial adjacent strings, are programmed by identifying pairs of three-level cells to be programmed that encode the strings of three bits and programming each pair of three-level cells.

A semiconductor memory device is provided. The semiconductor memory device includes a memory matrix having a plurality of memory cells arranged according to a plurality of rows and a plurality of columns and a plurality of bit lines, each bit line being associated with at least one respective column of said plurality. The semiconductor memory device further includes a bit line selection structure for selecting at least one among said bit lines and a voltage clamping circuit structure adapted to cause the clamping at a prescribed voltage of unselected bit lines adjacent and capacitively coupled to a selected bit line during a read operation.

Described herein is an output buffer including an output stage formed by a pull-up transistor and a pull-down transistor, which are connected in series between a supply line set at a supply potential and a ground line set at a ground potential, with an intermediate node connected to the output of the output buffer. The output buffer further includes a unidirectional decoupling stage arranged between the output of the output buffer and the pull-up transistor for decoupling the output from the supply line during the switching transients of the output buffer in such a way as to prevent the switching noise present on the latter from being transferred onto the output of the output buffer.
