  • Publication number: 20120182782
    Abstract: Methods for testing unprogrammed single transistor and two transistor anti-fuse memory cells include testing for connections of the cells to a bitline by comparing a voltage characteristic of a bitline connected to the cell under test to a reference bitline having a predetermined voltage characteristic. Some methods can use test cells having an access transistor identically configured to the access transistor of a normal memory cell, but omitting the anti-fuse device found in the normal memory cell, for testing the presence of a connection of the normal memory cell to the bitline. Such a test cell can be used in a further test for determining the level of capacitive coupling of the wordline voltage to the bitlines relative to that of a normal memory cell under test.

  • Patent number: 8213211
    Abstract: A method and system for improving reliability of OTP memories, and in particular anti-fuse memories, by storing one bit of data in at least two OTP memory cells. Therefore each bit of data is read out by accessing the at least two OTP memory cells at the same time in a multi-cell per bit mode. By storing one bit of data in at least two OTP memory cells, defective cells or weakly programmable cells are compensated for since the additional cell or cells provide inherent redundancy. Program reliability is ensured by programming the data one bit at a time, and verifying all programmed bits in a single-ended read mode, prior to normal operation where the data is read out in the multi-cell per bit mode. Programming and verification is achieved at high speed and with minimal power consumption using a novel program/verify algorithm for anti-fuse memory. In addition to improved reliability, read margin and read speed are improved over single cell per bit memories.

    Abstract: A low-pin-count non-volatile (NVM) memory to be provided in an integrated circuit. In one embodiment, the low-pin-count non-volatile (NVM) memory can use only one external control signal and one internal clock signal to generate start, stop, device ID, read/program/erase pattern, starting address, and actual read/program/erase cycles. When programming or erasing begins, toggling of the control signal increments/decrements a program or erase address and a pulse width of the control signal determines the actual program or erase time. A data out of the low-pin-count non-volatile (NVM) memory can be multiplexed with the control signal. Since the clock signal can be derived and shared from the system clock of the integrated circuit, the NVM memory need only have one external control pin for I/O transactions to realize a low-pin-count interface.

A write bitline of the NVM bitcell has a low resistance to handle large currents present during write operations.

    Abstract: Methods and systems for split threshold voltage programmable bitcells are disclosed and may include selectively programming bitcells in a memory device by applying a high voltage to a gate terminal of the bitcells, where the programming burns a conductive hole in an oxide layer above a higher threshold voltage layer in a memory device. The bitcells may comprise an oxide layer and a doped channel, which may comprise a plurality of different threshold voltage layers. The plurality of different threshold voltage layers may comprise at least one layer with a higher threshold voltage and at least one layer with a lower threshold voltage. The oxide may comprise a gate oxide. The bitcell may comprise an anti-fuse device. The layer with a higher threshold voltage may be separated from an output terminal of the bitcell by the at least one layer with a lower threshold voltage.

  • Patent number: 7995368
    Abstract: Embodiments of the present invention disclose a memory architecture for optimizing memory performance and size. Memory optimization is realized by configuring the memory to a particular logic state; that is, restricting memory data storage to either logic “0” or “1.” The opposite logic state, “1” or “0,” can be available through initialization and, therefore, may be presumed. Accordingly, the presumed, initialized logic state is available unless the configured logic state in memory changes the initialized data during memory access. Memory size reduction is realized by restricting physical memory to contain only cells that store data. Memory size can be further reduced by eliminating redundant data rows and columns. By reducing memory size, processing speed can be enhanced and power consumption reduced relative to conventional memory structures.

  • Publication number: 20110182101
    Abstract: A semiconductor memory device includes a security controller. When a one time programmable (OTP) device is programmed, the semiconductor memory device prohibits lock-status information pre-stored in an OTP lock register from being changed to an unlock status, such that it increases the stability of data stored in an OTP area. The semiconductor memory device includes an OTP device configured to determine whether or not data is changed according to a lock/unlock status when a program command is received, and an OTP controller configured to prohibit the lock status from being changed to the unlock status.

    Abstract: According to one embodiment, a differential circuit receives, as differential inputs, a readout signal read out from a semiconductor storage element and a reference voltage. An equalizing circuit controls, taking into account a state of a past input signal output from the differential circuit, the potential of the present differential signal output from the differential circuit. A sense amplifier detects a state of the differential signal output from the equalizing circuit. A state holding circuit holds a past state of the differential signal detected by the sense amplifier and supplies the state to the equalizing circuit.
